XHIV Cable

Description

XHIV cable is a medium-voltage power transmission and distribution cable featuring stranded copper conductors, cross-linked polyethylene insulation, a copper tape metallic screen, and a flame-retardant polyvinyl chloride outer sheath. It is primarily designed to meet Portuguese utility distribution grid for fixed installations in indoor or outdoor environments, and it is fully suitable for direct burial in the ground or placement inside cable ducts. 

These medium-voltage cables are manufactured in strict accordance with international standards including IEC 60502-2 for power cables, IEC 60228 for conductor specifications, and HD620 standards, while also complying with RoHS and REACH environmental directives. They typically support rated voltage classifications spanning from 3.6/6kV up to 18/30kV, supporting a maximum continuous conductor operating temperature of 90 degrees Celsius and a short-circuit threshold of 250 degrees Celsius.

Basic installation guidelines require maintaining a minimum bending radius of twenty times the overall cable diameter during active pulling and installation, which reduces to fifteen times the diameter once fixed in place.
