Abstract

The invention provides a cable. The cable comprises a core, filler and a covering layer which are coaxially arranged from inside to outside in sequence, wherein the covering layer comprises the following components in parts by weight: 60-70 parts of polyolefin elastomer, 20-30 parts of magnesium hydroxide powder, 30-40 parts of aluminium hydroxide powder, 1-2 parts of magnesium oxide powder, 1-2 parts of fumed silica, 0.2-1 part of coupling agent, 5-7 parts of plasticizer and 1-3 parts of cross-linking agent; and the inner layer of the covering layer is coated with a water repellent flame retardant coating. The cable can reach the flame retardant grade UL94-V0, has excellent fire resistance and water resistance, can be widely applied to various fields and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated overlay. [0003] 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. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0004] Therefore, cables play a very important role in various industries. In order to prevent accidents, their fire performance must be guaranteed, and...
