Conductors
Annealed copper, flexible stranded copper, tinned copper and aluminium are selected according to conductivity, flexibility, weight, termination and project requirements.
Cable Materials and Construction
Conductor, Insulation, Screen, Armour and Sheath Materials
Cable performance depends on the complete material system, not only the cross-sectional area. This guide shows how materials change across the main Jingfeng Cable model families.
Insulation
PVC, XLPE, PE, EPR, silicone rubber and halogen-free cross-linked compounds provide different temperature, electrical and environmental performance.
Screens
Copper-wire braid, copper tape and aluminium-plastic composite tape are available for control, instrumentation and charging cables when interference control is required.
Armour
Steel-tape armour is used in the listed 22 and 23 model families where mechanical protection is required. Armour is not automatically included in every cable.
Outer sheaths
PVC, PE, low-smoke halogen-free compounds, rubber, chloroprene, silicone rubber, thermoplastic elastomer and polyurethane are selected by installation duty.
How to Read the Tables
Model codes identify different constructions
YJ identifies XLPE insulation in the listed power and control cable families.
V identifies PVC insulation or sheath according to its position in the model code.
P identifies a screened construction; the exact screen type follows the full model.
22 / 23 identifies steel-tape armoured constructions in the listed product families.
R identifies a flexible stranded conductor where it is part of the model designation.
Model letters are read as a complete designation. Do not select a material from one letter without checking the full cable model and applicable standard.
Product Material Tables
Representative construction by model
These tables cover the models presented on this website. Custom and project-specific variants are confirmed on the technical datasheet before production.
