The cable owes its heat resistance to its structure and perfectly harmonised materials. 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.

LAPP, the global market leader for connection solutions and branded products in the field of cable and connection technology, has launched a new cable in the market – ÖLFLEX® HEAT 700 SC that can withstand a permanent temperature load of up to 700 degree Celsius.

The company is bringing the new ÖLFLEX® HEAT 700 SC to Hannover Messe 2025 (Hall 11, Stand C15) for the first time.

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.

“We have optimised the structure over the last few years. The interplay of both factors, i.e. the strands and the insulation, makes the temperature peak shift possible, says Product Manager Felix Graner.

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 300/500 volts.
