Remote signalling cable - with plastics insulated and colour marked strands and hollow space inside jacket filled with e.g. petroleum jelly

摘要

A remote signalling cable with plastics insulated and colour coded wires is claimed, in which the hollow space inside the cover is filled with a water repelling non-hardening medium based on a hydrocarbon or hydrocarbon mixt., such as petroleum jelly. The surfaces of all the wires are covered with the same amt. of marking colour per unit length, which is preferably one based on a polyolefin. The cable does not require equalizing of capacity differences.
