Conductors

Aluminium or copper conductors are optional. Conductors up to 630mm² will be circular, compacted & stranded and shall comply with IEC 60228 class 2. 

Conductor Screen

This will be an extruded layer of semi-conducting crosslinkable compound applied under simultaneous triple extrusion process over the conductor along with the insulation and the insulation screen. 

Insulation

This will be an extruded layer of XLPE applied over conductor screen under triple extrusion process along with conductor screen and insulation screen.

Insulation Screen

This will be a layer of semi-conducting crosslinkable compound which will be applied by triple extrusion process over the insulation.

Conductor screen, insulation and insulation screen usually adopt triple layer extrusion craftsmanship (which is a single high precision operation that eliminates the possibility of any contamination between the layers which could create irregularities in the electrical field). By careful material selection and special attention to process parameters, we produce the insulation screen layers with the required degree of stripping force as stipulated by the applicable national or international standard.

Metallic Screen

It will consist of a layer of copper tape applied helically with overlap over insulation screen. Other combinations of metallic screens as per customer ’s requirement can also be provided on request.

Over Sheath

An extruded layer is applied over the armour in case of armoured cables and over laid up cores in case of unarmoured cables. Outer sheath material can be either PVC, PE, HDPE or MDPE. our

medium voltage cables are normally supplied with red PVC over sheaths complying with BS 6622 or IEC 60502. Other colors may be provided to suit a range of installation considerations such as the effect of UV radiations and differing soil compositions. Anti-termite formulations can also be supplied in addition to graphite-coated over sheaths where on-site testing of the sheath is required.

Fire Performance on Cable Sheaths

Cables can also be supplied with special flame retardant PVC over sheaths to comply with the IEC 60332 standard. We can also supply cables with Low Smoke Halogen Free (LSZH) sheaths according to BS 7211 and BS 6724 standards or other equivalent international standards.

Operating characteristics

Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv.

Max.admissible operating temperature of the conductor:90ºC.

Max. short-circurt temperature of conductor shall not exceed 2500C. (5s maximum duration)

The bending radius of a single-core cable should not less than 20 times of the cable diameter.

The bending radius of a multi-core cable should not less than 15 times of the cable diameter.
