specification

Specification consists of three parts.

(1), rated voltage

(2), core number

(3), the nominal cross-section

Wires and control cables are generally rated voltage of 300 / 300V, 300 / 500V, 450 / 750V; low-voltage power cable rated voltage generally 0.6 / 1kv, 1.8 / 3kv, 3.6 / 6kv, 6/6 (10) KV , 8.7 / 10 (15) kv, 12 / 20kv, 18/20 (30) kv, 21 / 35kv, 26 / 35kv like.

Core number of wire and cable according to actual needs, and generally there are 1,2,3,4,5 core power cables, wires largely 1-5 core control cable with 1 to 61 cores.

Nominal cross-section is to guide the cross section of approximation. In order to achieve the required DC resistance, easy to remember and unified and specified a conductor cross-sectional close to an integer value. Our uniform provisions conductor cross-section has 0.5,0.75,1,1.5,2.5,4,6,10,16,25,35,50,70,95,120,150,185,240,300,400,500, 630,800,1000,1200 like. The emphasis here is the actual cross-section of conductor nominal cross is not a conductor, the actual cross-section smaller than the cross section of conductor Nominal many, there are a few larger than the nominal cross section. The actual production process, as long as the DC resistance of the conductor can meet the requirements, we can say that this cable is a cross-sectional compliance.
