Wire and cable model ZCN

Wire and cable Zcn refers to smokeless low-halogen flame-retardant Class C fire-resistant polychlorinated insulated interleaved flexible cable. ZCN cable, Z represents flame-retardant, C represents Class C, N represents fire-resistant, which together means flame-retardant Class C fire-resistant.

Model composition of wires and cables

1、 Purpose code - not marked as power cable, K is control cable, P is signal cable; 2、 Insulation code - Z oil-immersed paper, X rubber, V polyvinyl chloride, YJ cross-linked polyethylene; 3、 Conductor material code - not marked as copper, L is aluminum; 4、 Inner sheath code - Q lead wrap, L aluminum wrap, H rubber sheath, V PVC sheath; 5、 Derivative code - D does not drip, P dry insulation; 6、 Code of outer protective layer; 7、 Special product code - TH wet tropical zone, TA dry tropical zone; 8、 Rated voltage - unit KV

Difference between cable models ZR and ZC

ZR is the cable complying with the national standard and ZC is the cable complying with the public security fire protection standard. R cable and ZC cable are flame retardant cables, with Class A, B and C, and Class A is the best flame retardant; A/B/C refers to the grade requirements of the bundle flame retardant performance of the cable, which is an important indicator for assessing the flame retardant performance of the cable.
