PVC CABLES

 

"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 below :

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.
