Power cable Product type, model specification and application
Feb 28, 2018

The main products of power cables are bare wires, insulated wires, control cables, power cables, overhead insulated cables, flame-retardant cables, fire-resistant cables, etc., the following respectively on its implementation standards, model specifications, the use of a brief introduction.


1. Bare Wire


My company produces bare wires including aluminum stranded wire, steel core aluminum stranded wire, anti-corrosion steel core aluminum strand, hard copper stranded wire, soft copper stranded wire.


The name method of the product model of the bare wire type, generally follows the rule in table 1:

1.1 Aluminum stranded wire, steel core aluminum strand, anticorrosion steel corealuminum Strand


Implementation of the standard: gb/t1179-1999 "round wire concentric stranded overhead wire." This standard is equivalent to the use of international standard iec61089-1991 "round line concentric stranded overhead wire", instead of the original national standard gb1179-83 "aluminum stranded wire and steel core aluminum stranded wire" and gb9329-88 "aluminum alloy strand and steel core aluminum alloy stranded wire."


Model specification: See table 2.

Note: (1) G1 for ordinary strength steel wire, G2 Express high strength steel wire, G3 Express high strength steel wire;


(2) A indicates that the galvanized layer of the steel wire is a Class A, b indicates that the galvanized layer of the steel wire is B, and its zinc layer is thicker than a grade.


(3) The most commonly used steel core aluminum stranded wire model for JL/G1A.


Corrosion-resistant steel-core aluminum stranded wire anti-corrosion forms are:


(1) coating preservatives, according to the number of preservative coating is divided into light anti-corrosion, anti-corrosion, heavy corrosion.


(2) galvanized wire using zinc-5% aluminum-rare earth alloy coating anti-corrosion.
