Nicco manufactures 1.1kV & 3.3 kV LV XLPE Cable using SIOPLAS Technology

Sioplas Technology - SILANE Process : Silane Crosslinkable Polyethylene compound is curable by exposure to moist conditions for insulation of Power Cables. This compound is based on a high molecular weight polymer and it is especially developed for Low Voltage cable insulation.

This compound utilises the system for Crosslinking of Polyethylene known as SIOPLAS. it is a two component system comprising of silylated ethylene polymer known as the graft copolymers and a masterbatch material containing a crosslinking catalyst, the two materials normally being added in the ratio of 95:5. This system thus attain a high level of crosslinking in the processed form and the finished product has all the properties associated with crosslinked polyethylene cable.

Advantages

• Higher current rating permits to select lower size of XLPE cable compared to PVC cables.

• Higher short circuit rating than PVC cables.

• Resistant to heat deformation while PVC is prone to heat deformation.

• Repetitive short circuit / overload condition is reliable.

• Lower Dielectric Loss.

• Lighter weight considering lower overall diameter.

• Ease of handling & jointing.

Conductor : Conductors of nominal area less than 16 sq mm are circular only. Conductors of nominal area 16 sq mm and above may be circular or sector shaped.

Insulation : The conductors are insulated with XLPE (Cross linked Polyethylene) by extrusion process.

Core identification : Cores are identified by coloured XLPE insulation.

Inner Sheath : The cores of multicrore cables are laid up and surrounded by PVC covering either by extrusion or by wrapping.

Armour : Armouring is of two types - galvanized round steel wire or galvanism steel strip

Outer Sheath : This is provided by means of extruded Polyvinyl chloride (PVC) compound conforming to the requirements of Type ST-2 compound of IS: 5831.
