Construction & Configuration
Layer-by-layer breakdown of conductor, insulation and color coding.
Conductor — Bare Copper
Solid (BV) or fine-strand (RV) bare copper conductor sized to the specified cross-section.
Single Insulation Layer — PVC
A single extruded PVC layer is the only covering on the conductor — there is no separate outer jacket.
Insulation Color Coding
Insulation color (brown / blue / green-yellow) identifies Live, Neutral or Earth per harmonized standard.
Conductor Temperature Grade
PVC compound formulated for continuous 70℃ service, or upgraded to a 90℃ heat-resistant grade for internal wiring.
No Outer Jacket
Intended for use inside conduit, trunking or equipment enclosures that provide the mechanical and environmental protection.
Surface Marking
Standard, rated voltage and manufacturer marking are printed along the insulation surface for traceability.
Standards & Test Documentation
Design standards, certification and voltage/temperature rating information.
GB 5023
Produced in accordance with GB 5023, the Chinese national standard for PVC insulated cables and their cores.
CCC Certified
Independently tested and certified under the China Compulsory Certification (CCC) scheme for the domestic market.
450/750V · 70℃/90℃
Single-insulated design for internal wiring inside conduit, trunking or equipment enclosures; not intended for direct burial or exposed outdoor use.
