High-performance cables for industrial and commercial power transmission. Built with high-purity aluminium or copper conductors and premium insulation, they ensure reliable performance and long service life, even in demanding conditions.
Applications: Power stations, factories, buildings, infrastructure.
XLPE INSULATED PVC SHEATHED CABLES (IS: 7098 PART- I)
The conductor is insulated with a thermoplastic material, namely polyethylene, which is a linear chain compound. After undergoing a special curing process, the linear chain is transformed into a cross-linked thermosetting structure. This material provides exceptional electrical, thermal, and mechanical properties, including excellent dielectric strength, higher continuous current rating, and superior resistance to thermal ageing.
ADVANTAGES of XLPE Cables over PVC
- Excellent electrical & physical properties : High resistance to thermal deformation and the ageing property of XLPE cables provides higher continuos and short circuit current capacity of cable .
- Higher current carrying capacity : Current carrying capacity of the XLPE cable is about 30% higher than PVC cable of same size.
- Lower permitinity : Permitinity of XLPE is 2.3 and that of PVC is 7.
- Lower di-electric loss : XLPE has lower di-electric loss than PVC cables
- System protection : Charging current is considerably lower than PVC cable , which allow coarse setting of network protection system .
- Emergency over loading : Can be loaded for higher current and long duration .
- Resistance to heat : Because of cross linking, structure provides excellent resistance to ozone & heat.
- Mechanical resistance : Due to thermosetting, conversion exhibits better mechanical property over PVC
- Environmental & surrounding protection: Excellent mechanical feature provides protection against external effects. Resistance to acid & alkalies is excllent .
- Rating Features : XLPE Carrie more current than PVC counterpart.
- Light Weight : Due to low specific gravity of XLPE (0.90) , cables are comparatively lighter in weight than PVC (1.35 – 1.55)
- Cost Saving : Due to low weight and less dimension , laying and corresponding accessories becomes cost effective .
