Power Cables (Armoured / Unarmoured - PVC / XLPE)
GRID INDIA manufactures a wide range of Armoured
Cables, Armoured Power Cables, Armoured Electrical Cables, PVC Armoured
Cables and XLPE Armoured Cables. XLPE means cross-linked polyethylene or
vulcanized polyethylene. The basic material is low density polyethylene.
Polyethylene is a thermoplastic material consisting of long chain of
hydrocarbon molecules. At elevated temperatures these molecules tend to move
relative to one another so that the material becomes increasingly deformable
and will eventually melt at the temperature around 110°C.
By means of process similar to the vulcanization of rubber the polyethylene
molecules can be cross-linked. The process of cross-linking or vulcanization
consists of producing chemical bonds at interval between the long molecular
chain to give a “ladder” effect which prevents slippage between
molecules as a result of cross-linking the material becomes heat resistant
and does not soften at higher temperatures. Further it has better resistance
to stress cracking and good resistance to ageing in hot air. With the change
of structure there is no adverse effect on electrical properties.
Advantage of “GRID CABLES” XLPE Cables
- Dielectric losses are very small
- Higher current carrying capacity
- Higher short circuit rating 250°C as against 160°C for PVC
- “GRID CABLES” XLPE can retain flexibility down upto - 40°C
- Jointing and Termination is easy
- Light in weight
- They are not prone to fatigue damages due to vibrations or loading
cycles
- Has better resistance to most chemicals, oils, acids, etc
- Can be installed along cable routes without elevation limitations

Control Cables (Armoured / Unarmoured - PVC / XLPE)
A wide range of Control Cables (PVC Insulated &
Sheathed Flexible Cables) are available with us. These control cables have
high tensile strength and accurate resistance to high temperatures. These
cables work in both dry and moist conditions. We offer them in black/gray
core colours and gray, black and white sheer colours. They are highly
flexible for application in different electrical environment. These control
cables used in tool machines, steel production units, electrical substations
etc.
