New compounds minus the lead oxide stabilisers

In EPDM compounding the rubber resin is mixed with other additives to improve the mechanical and electrical properties. Lead chemicals are used as stabiliser in today’s commercially available EPDM compounds for medium voltage (MV) insulations for water-resistant long-lasting perfor- mances. In the European community, red lead oxide is listed in REACH SVHC (Substances of Very High Concern), forcing MV cable producers to substitute the material with a non-leaded alternative.

Mixer SpA has developed an MV EPDM compound that no longer contains lead oxide stabilisers. The material exhibits both electrical and physical properties that are comparable to leaded compounds. The properties have already been tested on cables complying with 100 per cent of European specification requirements. Based in Northern Italy, the company can produce 30,000 tons per year and exports, to more than 20 countries worldwide, its range of products, including insulation, jacketing and bedding; for low and medium voltage power cables; peroxide and irradiation crosslinking; halogen free, fire resistance, low smoke and oil resistant. SCHLEUNIGER Inc, an international manufacturer of high-precision wire processing machines, recently displayed its newest cut and strip machine, the MultiStrip 9480. The machine’s high resolution indexing cutter head and programmable rotary incision capability set the benchmark for high precision processing of coaxial and other shielded cables. The MultiStrip 9480 family offers various machine versions to meet specific production needs. With many additional options and accessories, the MultiStrip 9480 can handle a range of applications. Designed with efficiency in mind, the SmartBlade system and magnetically held guides increase output and maximise production by reducing changeover times. Another new product is the PreFeeder 4300, a compact cable feeding system for cable reels weighing up to 400kg (880lb.). The system distinguishes itself through its simple design and ease of use. The shaftless design for easy loading and unloading of reels along with motorised axes allow reel handing with just one person. The machine’s high feeding dynamic allows for higher production rates and increases the economic efficiency of the entire processing line. There is also the CT 65, a hydraulic press with 15 tons of crimping force. It features quick-release mechanisms for fast die changes as well as programmable die close and open positions to minimise stroke and

processing times. Up to 30 jobs can be stored in the memory for easy recall and programs can be secured with a key switch. The UniCrimp 100 is a benchtop crimping machine that delivers up to two tons of force. The safety guards can be completely opened to allow easy access to the working area along with simple, fast changeover, adjustment and set up times. The UniCrimp 100 accepts most applicators on the market and provides quality crimping for wires up to 6mm 2 (10 AWG). ❍ MultiStrip 9480 from Schleuniger
