This is just one of the measures being introduced by the energy commission to regulate the operations of electrical engineers, to uphold professional standards, and to protect life and property. The commission has instituted a certification scheme for electricians across the country. Its principal programme officer, Solomon Sarpong, has said that electricians who fail to comply with the directive will be prosecuted. “The certification programme seeks to inject some professionalism into the electrical wiring industry. Electrical wiring has a lot to do with the safety of persons and property because faulty wiring consequently causes a lot of fire outbreaks, among others. “The Electrical Wiring regulation 2011 (LI 2008) passed by parliament in 2012 has three key objectives: who qualifies Tyre cord demand tires Belgian steel wire and cable maker Bekaert reported that its 2014 operating profit rose at a slower rate than anticipated, blaming a slowdown in the Chinese market for tyre reinforcing wire. The group, whose steel wire is said to feature in 25 per cent of the world’s automotive tyres, said earnings before interest and tax (EBIT) was $195 million in 2014. However, sales were largely in line with analyst expectations, and core profit was above the consensus. “Tyre cord activities in China did deteriorate towards year-end 2014 and impacted our annual results on some key performance criteria, compared to the most recent analyst estimates,” Bekaert confirmed. In December, Chinese manufacturer Shougang issued a profit warning, stating that selling prices for steel cords had fallen in the second half of the year.

Local talent for local supply

Power exchange During January 2015 Tajikistan’s 220kW and 110kW networks from Sangtuda-1 and Sangtuda-2 hydroelectric power plants reportedly transmitted nearly 55GWh of electricity to Afghanistan: 25GWh more than in the same period in 2014. However, the electricity rationing that was introduced in Tajikistan on 1 st October, and which resulted in the reduction of electricity supply in rural areas to fewer than 12 hours per day, is still in effect in the country. The Tajik president, Emomali Rahmon, has since ordered an increase in supply to residential customers in rural areas to 13 hours – six hours in the morning and seven hours in the evening.

THE UAE ministry of economy’s latest report states that copper exports contribute approximately $1 billon to UAE’s trade surplus. It has been revealed that there is a difference of just $5 million between volumes of copper cable exports of the USA ($1.33 billion) and the UAE ($1.325 billion), taking the UAE to a global fifth position, after the USA. Participants at Wire and Cable Arabia 2015 acknowledged the investment opportunities offered in the sector in the UAE and wider region, despite a slowdown in other parts of the world. Satish Khanna, the general manager of Al Fajer Information and Services, organisers of Wire and Cable Arabia 2015, said: “The cable industry in the UAE is competitive, mature, expenditure-driven and caters to almost all sectors of the economy. It has gone through a phase of rapid growth that has encouraged new players to enter the sector. “The key growth drivers of the UAE’s cable industry are the booming infrastructure and utilities spending, telecom liberalisation, demand for electricity, government subsidies, and export opportunities.” Mr Khanna explained: “The types of cables produced in the UAE are energy cables, instrumentation cables, power and control cables, industrial cables and communications cables. Wire and Cable Arabia 2015 was able to connect serious buyers with local manufacturers to accelerate export processes.”

New launch for E-marine

E-MARINE, a provider of submarine cable installation and repair solutions in the Middle East and sub-continent region, has unveiled ambitious plans to expand its fleet of cable ships in 2015, with the first ship, the CS Maram , beginning dock trials ahead of its maiden voyage this year. The CS Maram , which was built in Abu Dhabi, UAE, has been designed to manage the installation and maintenance of all types of submarine cables, including fibre optic telecommunications cables and energy cables. The ship is expected to successfully complete dock trials and be ready for launch within the coming months. E-marine’s planned fleet expansion will see the addition of further multi-purpose vessels in the coming years, boosting its coverage across the region, with a particular focus on East Africa and the wider region. The expansion will help strengthen the firm’s presence in the high-growth subsea cable market and undertake activities to stem demand from telecoms and energy sectors. Omar Jassim Bin Kalban, managing director and chief executive officer, said: “Our commitment to increasing market share in the region will see a significant expansion to our fleet. By

increasing our number of vessels, we are positioning E-marine to provide a faster, wider and far reaching service to cable owners through reduced transit times and closer proximity to cable systems. “This investment in our fleet signifies a renewed confidence and optimism in the region’s digital future, and will support the roll-out and maintenance of submarine cables. The CS Maram is a state-of-the-art cable ship that will provide our customers with the latest subsea cabling technology.” The fully loaded maintenance and installation vessel will incorporate a submarine robot or ROV (remotely ❍ The CS Maram during dock trials in Abu Dhabi

operated vehicle) that will enable the vessel to undertake pre-inspections and surveys of the seabed and cut trenches to bury the cable. Once the CS Maram is fully operational, it will generate direct employment opportunities in the region. The company already has a highly skilled and diverse workforce of more than 20 nationalities, and will be seeking an international crew of captains, seamen and technicians for the new ship from across the region to take up positions on board the vessel.

Private equity firm Actis, and Mainstream Renewable Power, have launched a pan-African renewable energy generation platform, Lekela Power. By 2018 Lekela Power will provide between 700MW and 900MW of wind and solar power across Africa. Mainstream and Actis have two previous partnerships, in South Africa and Chile. Lekela Power will operate in a similar fashion to the existing partnerships, with Mainstream taking responsibility for project management and plant operation and maintenance. Mainstream has announced the start of construction for three wind farms in South Africa to form the core of the Lekela platform. The projects, with a combined capacity of 360MW, are located in the country’s Northern Cape and were awarded to Mainstream as part of the government’s renewable energy procurement programme. They are expected to reach commercial operation beginning Addressing the power balance in Africa

加纳无电气布 线认证的新建 筑将切断供电 从 2015 年 2 月 25 日起，加纳没有电气布 线认证的所有新建筑将从国家电网切断 电力供应。根据加纳能源委员会表示， 这是电气工程师管理操作的措施之一， 旨在坚持专业标准来保护生命财产。能 源委员会针对全国的电工设立了一个认 证计划。首席计划官 Solomon Sarpong 表示，那些不遵守指令的电工将被起 诉。 “认证计划是为了向电气布线行业注入 专业精神。电气布线对于生命财产至关 重要，因为不当的布线会造成火灾等后 果。” “ 2012 年国会通过的 2011 电气布线法 规 ( LI 2008 ) 有三大主要目标：具有 资格从事任何电气布线的人员，如何布 线，以及布线采用的何种原材料，”他 补充说。 “为了有效实施上述几点，能源委员会 把电气布线和供电联系起来。如果建筑 不是由一个具有资格认证的电气专业人 员 ( CEWP ) 完成的布线，并且最终还 发布了布线完成证书，那么该建筑将不 能连接到加纳电力公司的电网中。” 比利时钢电线电缆制造商 Bekaert 报道 称，公司 2014 年营业利润增长速度不如 预期，原因在于中国市场对轮胎钢丝的 需求放缓。 据悉，全球 25% 的汽车轮胎采用了集团 的钢丝， 2014 年息税前利润 ( EBIT ) 为 1.95 亿美元，低于路透社分析调查的平 均预测结果。但是销售额基本与分析的 预期相符，核心盈利高于共识。 “中国钢帘线市场低迷一直持续到 2014 年底，相比最近的分析预估，影 响了我们年度业绩的一些关键绩效标 准，” Bekaert 证实。去年十二月，中 国制造商首钢发出盈利警告，指出钢帘 线销售价格下半年已经下降。 轮胎钢帘线需求 疲软 Bekaert NV – 比利时 网址 : www.bekaert.com

IN the area of raw materials conveying, motan-colortronic China will present its new Metro G range of material loaders at the Import and Export Fair, Guangzhou, PR China in Hall 5.1 at stand D61 in June. The new Metro G material loader range

motan-colortronic China will exhibit the whole range of solutions for plastics processing applications. The focus will be on four major product areas: The first is drying with compressed-air dryers and dry-air dryers. The second is conveying systems: the new Metro G material loaders can be integrated in automatic central conveying systems, which will reduce costs and improve productivity and competitiveness. The third area is dosing and mixing systems such as the new Miniblend V which will also be launched at the exhibition. It is a

volumetric dosing and mixing unit for small-quantity dosing with high demands on dosing consistency. Last are control systems supervising material processing to ensure quality products. Developed by motan engineers, Metro G combines the latest technologies from colortronic and motan and enhances these systems with a number of new features. The Metro G is claimed to be one of the most comprehensive and flexible material loaders on the market. Its modular building block system allows users to create and configure the optimal material loader for their specific application. For example, a standard material loader unit can be expanded into a cleanroom version just by adding a special vacuum diaphragm valve. A dust removal module removes fine dust at the material loader, essential for some critical engineering plastics where absolutely no dust is allowed to enter the process. The system can also be fitted with modules with a tangential material inlet to provide a cyclone effect for processing those materials where separation of coarse dust is required. The volumetric Miniblend V dosing and mixing unit offers mixing quality and consistently accurate dosing. Mounted between the machine hopper and the feed throat of the plastics processing machine, the unit requires very little space. Disc dosing with the Miniblend V gives the user real volume dosing which guarantees a very high dosing accuracy – even for very small dosing quantities. Three different disc sizes as well as dosing modules made of materials such as stainless steel or glass, and special wear-resistant discs for hard and abrasive materials are available. Module exchange is quick and easy and thus allows fast colour changes. The Miniblend V is designed to dose free and normal-flowing materials and micro-batches. The unit can be operated by motan’s volumetric controls Volu MC or Volunet MC, which is equipped with an Ethernet interface. motan-colortronic China – China Website : www.motan-colortronic.com

WHEN looking for a cleaning system for wires and cables etc, you can often be faced with a dilemma. Which method, in general mechanical or wet-chemically, is suitable for the desired surface quality? Budget or available space is limited, and the range of manufacturers of in-line cleaning systems as well as the current market solutions is manageable. The appropriate method is difficult to determine at first glance. As a result there is often an attempt to construct and implement your own solutions only to find that the outcome is, despite intense input of time and material, inadequate. Basically, the definition of the cleaning target and the analysis of the surface texture should be at the beginning of the search. Only when these points are defined, the choice of the suitable method and, if necessary, a suitable cleaning agent, can be carried out. As mentioned, usually a subdivision in ‘mechanical cleaning’ and ‘chemical cleaning’ is made, whereby nearly all mechanical cleaning methods can be combined with the chemical cleaning. On ‘mechanical cleaning’ the contamination is removed by the mechanical frictional force of normally solid cleaning materials such as brushes, textiles and microfibres. To Wire cleaning – the dilemma

remove gross contamination from the wire surface the cleaning with brushes or textile materials is very effective. Since the surface characteristics of the wire are far from ideal due to, for example, fine cracks and defects, these methods quickly reach their limits. ‘Chemical cleaning’ means, in most cases, that a fluid exposure performs the cleaning. The performance of these methods is considerably improved by increasing the velocity of the liquid by means of high pressure, ultrasonic or steam relaxation. Cleaning processes with liquids, supported by ultrasonic, high pressure or steam, can substantially meet the challenging task of removing dirt even from the smallest surface defects. Finally, the effectiveness of the cleaning process depends on how targeted the cleaning power (force or impulse) can be applied to the contamination for a certain time. Since the choice of the appropriate cleaning method is determined by many other factors, a comprehensive analysis of all parameters should be undertaken. This is precisely the approach GEO-Reinigungstechnik GmbH has selected. For the last two decades GEO has explicitly dealt with the cleaning of continuous profiles such as wires, ribbons, strands and cables. The procedures can be tested under near-production conditions at GEO’s test laboratory and from the knowledge gained, suitable solutions can be selected and implemented.
