Description

technical field

[0001] The invention relates to the technical field of cable manufacture, in particular to a formula for a fireproof cable insulating layer material. Background technique

[0002] As we all know, cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, and aluminum alloy cables. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. Because the traditional cables do not contain any fire-resistant ingredients, the surface of the cables tends to age over time. Once exposed to fire, they are easily ignited and cause a fire with serious consequences. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a cable formula with reasonable material matching, low cost and fireproof function, tha...
