This guide covers 0.6/1 kV steel-tape armored power cables, commonly designated YJV22, for distribution networks requiring mechanical protection. It outlines construction, including XLPE insulation and PVC sheath, cross-sectional ranges, direct-burial and complex-terrain applications, thermal limits, and compliance with IEC, BS, and GB standards.

Steel-tape armored power cables rated at 0.6/1 kV, commonly designated YJV22, are used in distribution networks where mechanical protection and electrical stability are critical. Their construction is intended to withstand soil pressure, ground movement and other physical stresses in demanding installation environments. The main technical specifications, application conditions and compliance requirements are set out below.

Technical specifications and construction

The 0.6/1 kV steel-tape armored cable series is designed for AC power distribution systems with a rated voltage Uo/U not exceeding 0.6/1 kV. Its structure is configured to address demanding physical conditions while maintaining electrical performance.

Item	Technical description
Rated voltage	0.6/1 kV
Conductor material	Class 1/2 annealed bare copper, solid or stranded
Insulation material	Cross-linked polyethylene (XLPE)
Armor type	Steel-tape armor (STA)
Sheath material	Polyvinyl chloride (PVC)
Cross-sectional area range	1.5 mm² to 630 mm²
Standards	IEC 60502, BS 7870, GB/T 12706

Engineering applications and environmental performance

The cable is intended for installation scenarios that impose elevated mechanical stress. The steel-tape armor supports reliable operation in the following conditions:

Direct burial: The cable can withstand mechanical stress from soil pressure and surface movement.
Complex terrain: It is suitable for slopes, moving ground and vertical or inclined installation.
Multi-environment use: It supports indoor and outdoor installation and maintains stability in damp environments.

On thermal performance, the maximum conductor temperature is 90°C during normal operation. The cable can withstand 130°C in emergency conditions and up to 250°C under short-circuit conditions lasting no more than five seconds.

Quality certification and production standards

The series is produced in line with international and national standards including IEC 60502, IEC 60228 and GB/T 12706.1-2008. It also carries ISO 9001, ISO 14001 and OHSAS 18001 system certifications, together with CCC, CE and CB market-access certifications.

Custom variants can be specified for flame-retardant, fire-resistant and low-smoke zero-halogen performance, subject to production design and the requirements defined before procurement.

Frequently Asked Questions

What is the difference between steel-tape armor (STA) and steel-wire armor (SWA) in cable selection?

Steel-tape armor is mainly used to withstand radial pressure, such as in direct burial. Steel-wire armor is more suitable for applications requiring greater axial tensile strength, such as vertical installation or cable hoisting. Selection should be based on the force characteristics of the installation route.

What is the minimum bending radius for this cable series?

According to technical specifications, the minimum bending radius after installation should be no less than 12 times the cable outer diameter (O.D.) to prevent damage to the insulation layer or armor structure.

When are cables with custom performance required?

If the cable is installed in densely populated areas or locations with high fire-safety requirements, custom models with low-smoke zero-halogen or fire-resistant characteristics are recommended. Specific performance requirements should be defined before procurement so that producers can carry out targeted design.
