Insulation Screen
Extruded Semi-conducting compound. Minimum thickness 0.5 mm and the maximum volume resistivity of 5000 ohm-cm at 20°C and 25000 ohm-cm at WC The screen is tightly fitted to insulation to exdude all air voids and can be easily hand stripped on site.

Conduction Water Blocking Layer
Semi-conductive water blocking tape provided over the insulation screen which will swell up under the influence ofmoisture or water.

Metallic Screen
Copper wires applied over the conducting water blocking layer. Minimum cross section of concentric conductor as shown in table 2. Copper tape with minimum thickness 0.1 mm and maximum 0.3mm applied over copper wires.

Water Blocking Layer
Non-conducting water blocking tape provided the metallic screen which will swellup under ihe influence of moisture or water.

Inner Sheath
Extruded black PVC, capable for operating continuously maximum temperature of the cable. Thickness of inner sheath as shown in table 3.

Outer Sheath
Extruded red PVC, suitable tar exposure to sun-light or other local atmospheric environments and for the operating temperature of the cable.
