67 th IWCS conference

The RC controller is supplied xed to the unit, but can be detached and mounted remotely up to 60m away from the test module/electrode. It has a large, bright, alphanumeric display/user interface and can be rotated in its bracket to accommodate di erent viewing angles. The display makes con guration of the equipment easy: all con guration parameters can be changed directly from the front panel menu structure. Once con gured, the system can be passcode protected. In cases where a local display is not required, or centralised process control is desired, the equipment can be controlled directly from PLCs or computers using Modbus RTU (RS-485 full duplex). Optional communication protocols include Ethernet/IP, Pro net and Pro bus, Modbus TCP and analogue communications, making the equipment compatible with previous Clinton equipment with analogue control. Clinton will be exhibiting examples of the new B-series spark testers, including the new model TSTB, the 10kV DC wireless spark test system for cable twinners. The control unit remains outside the twinning bow and communicates with the high voltage test module located within the rotating machinery. The company will demonstrate this equipment on a model twinner. Clinton Instrument Company will also exhibit and demonstrate the ST-CAL automatic spark tester calibration system. The ST-CAL system will calibrate high frequency AC, mains frequency AC, and DC spark testers to all major speci cations. Calibration is automatically performed and documented on all of Clinton’s new B-series spark testers and selected A-series models. Manual or assisted calibration can be performed on older Clinton units, as well as equipment manufactured by others. When paired with Clinton’s model SM sensitivity tester, a complete calibration solution to IEC and NEMA standards is provided. Clinton Instrument Company – USA Website : www.cicsparkers.com Supported by its Dutch cooperation partner Inhol, Melos supplies cable manufacturers around the world, meeting their individual requirements. The portfolio includes a wide range of thermoplastic and cross-linkable compounds for cable insulation and sheathing. In addition, Melos is an expert in manufacturing internationally proven FM bedding compounds. Inhol BV Stand: 417

After a four-year cooperation, the acquisition of Inhol has been successfully executed. From 1 st January 2018, Inhol is o cially part of the Melos group. With its special insulation and sheathing compounds in the Mecoline TP and Mecoline RDX product portfolio, Melos and Inhol now serve markets with high requirements in terms of low-temperature exibility. These demands are particularly prevalent in regions with extreme climatic conditions, such as northern Russia.

The company has an o ce in Wuhan, China, to cover the whole of Asia for technical assistance and maintenance. Cersa-MCI – France Website : www.cersa-mci.com ▲ A range of measurement and control systems from Cersa-MCI Clinton Instrument Company is a specialist in spark test technology for the wire and cable industry, and inventor of the high frequency sine wave spark tester. Following the success of the model HF-15B high frequency sine wave spark tester, Clinton’s range of DC spark testers are being redesigned to make use of the advancements of the B-series. Among the features of the B-series are the split-electrode design for easy string-up, and digital signal processor (DSP) based voltage regulation and fault detection. The fault detection circuit has been upgraded and test voltage is now monitored directly from the electrode, instead of a transformer winding. The fault circuitry di erentiates between four types of fault conditions: simple pinholes, a series of closely spaced pinholes, direct metal contact from the centre conductor to the electrode, and gross lengths of bare wire.

Potential areas of application for these cables include ships, wind turbines, conduits and oil rigs. Their exibility means they are suitable for use in more demanding moving applications. The low brittleness temperature of certain Mecoline products for Arctic conditions ensures low material embrittlement, even when used in environments with intense temperatures. There are the optimum values with regard to thermal expansion, cold impact and the cold bend test, which make this Mecoline product range a choice for applications requiring exibility at low temperatures. Furthermore Melos o ers bedding compound solutions. The introduction of the new CPR urges cable manufacturers to review their cable designs. Melos is committed to support the cable industry, based on 30 years of experience with halogen-free, ame-retardant compounds. In accordance with the new product regulations (CPR), priority is given to saving lives, containing the blaze, and reducing damage in the case of re in a building. Cables play an important part in this process. Results were obtained recently by cable factories in the USA and Europe with speci c bedding compounds containing an e ective combination of mineral ame retardants. Test results with cerami able tapes have not reached the performance and price level of competitively priced, highly ame-retardant bedding compounds. Melos believes that, in the coming decades, matters such as heat release, ame propagation, toxic gases, low ▲ Melos and Inhol now serve markets with high requirements in terms of low-temperature exibility
