LAPPP has announced the launch of the new cable “ÖLFLEX® HEAT 700 SC” that can withstand temperatures of up to 700°C.
Where “normal” temperatures prevail, “normal” cables, for example with a PVC sheath, are also sufficient. They are generally designed for maximum temperatures of around 70°C to 90°C and are therefore suitable for use in industrial plants or factories with more normal temperatures. However, wherever temperatures permanently exceed the 100°C mark, heat-resistant cables are required.
The cable owes its heat resistance to its structure and perfectly harmonised materials. While the strands of its predecessor were made of pure nickel, LAPP uses nickel-plated copper conductors for the new single-core cable. The insulation of the cable consists of a multiple glass fibre covering and a glass fibre braid.
Compared to a pure nickel conductor, the fine-stranded, nickel-plated copper conductor also achieves better electrical conductivity, higher dielectric strength and also allows smaller conductor cross-sections to be selected than with its predecessor. The halogen-free and flame-retardant material composition reduces the risk of fire propagation in the event of a fire.
Single-core cables are used wherever energy and temperatures are particularly high and fixed installation and wiring is required. For example, in foundries, heating modules or electric cookers as well as in smelting works and steelworks, but also in the chemical industry or in machine and equipment construction. The new product is designed for a voltage of 300/500V.
