Abstract
Description
technical field
[0001] The invention relates to the technical field of cable cutting and retracting, in particular to a retracting device for a high-temperature and high-voltage resistant cable that is convenient for cutting. Background technique
[0002] A cable is a kind of electrical energy or signal transmission device. It is usually a rope-like cable twisted by several or groups of wires. Each group has at least two wires. Each group of wires is insulated from each other and often surrounds a center Twisted, the entire outer surface is covered with a highly insulating covering. The cable has the characteristics of internal energization and external insulation. The cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, Fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc., are composed of single-strand or multi-strand wires and insulating layers...
