"PAWAN-CAB" offers complete range of Power & Control Cables
from 1.5 sq.mm to 1000 sq.mm. single core cables, multicore cables
upto 400 sq.mm. & copper control cables upto 61 cores. The above
cables are also manufactured with special compounds as enlisted
HR PVC :
Heat resisting PVC
compound has good thermal stability at an accelerated process temperature.
The rate of degradation of HRPVC compound with time under the influence
of temperature is less. It has high thermal stability can withstand
high continuous temperature which is
an indication of performance of the cable at normal and elevated
temperature in actual usage.
The cables with HR PVC compound can work continuously at an operating
temperature of 85 Deg. C. The usage of HR insulated cables is recommended
in humid atmosphere and at places with constant high temperature
than normal temperature. The current rating of the HR insulated
cables is higher than the general PVC insulated cables.
FRLS Compound :
Fire Accidents in
cable galleries and other vulnerable areas like power plants and
industrial complexes and in public places like theatres, hotels
and airports, etc. have demonstrated the need for reliable electrical
installation, resistant to fire and ability to operate during a
fire without propagating it. The use of correct electrical installation
makes evaluation of buildings easier, minimizes the element of panic
and enables the emergency services do their job efficiently, significantly
aiding damage control operations and reducing loss of life and property.
Electric Cables supplying these circuits must be manufactured and
tested for certain standards and specifications concerning their
behaviour in fire. Flame Retardant Low Smoke (FRLS) cables, which
are manufactured using specially developed FRLS compound for sheathing,
are resistant to ignition and flame propagation, and reduce smoke
emission and release of acid fumes.
XLPE COMPOUND :
XLPE means cross linked polyethylene or vulcanised
polyethylene. The basic material of XLPE is low density polyethylene.
Polyethylene is a thermoplastic material consisting of long chain
Hydrocarbon Molecules at elevated temperature and these molecules
tend to move relative to one another so that the material becomes
increasingly diformable and will eventually melt at a temperature
of around 110 Deg. C. By means of process similar to the Vulcanisation
of Rubber the PE Molecules can be cross linked. The process of cross
linking or vulcanisation consists of producing chemical bonds at
intervals between the long molecular chain to give a "Ladder" effect
which prevents slippage between molecules. As a result of Crosslinking,
the material becomes heat resistance and does not soften at higher
temperature. Further it has better resistance to stress cracking
and good resistance to ageing in hot air with the change in structure.
There is no adverse effect on electrical properties. XLPE Cables
are excellent in electrical, thermal, mechanical and chemical properties.
