XLPE Power Cables

We are listed among the most prominent XLPE Power Cables Manufacturers in India. The unmatched quality and inexplicable performance of the LT XLPE Cables have played a vital role in the enhancement of the demand in the market. Customers are also facilitated with the availability of the XLPE Insulated Power Cable in varied sizes, lengths and diameters so as to meet the specific requirements. Orient cables is manufacturing LT- Power Cables with XLPE insulation of voltage grade upto 1.1KV conforming to various Indian (IS-7098/1-1988) and International Standard Specification. CROSS LINKED POLYETHYLENE (XLPE) XLPE means cross-linked polyethylene or vulcanize 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 or rubber the polyethylene molecules can be cross-linked. The process of cross linking or vulcanization consists or 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. LT-XLPE CABLES ARE SUPERIOR OVER PVC CABLE SINCE THEY

• Have longer life as compared to conventional PVC Cables.
• Have higher conductor temperature rating i.e. 90°C as against 70°C of PVC and hence higher current rating.
• Have higher emergency overload capacity than PVC Cables (upto 60%).
• Have max. Temperature limit under short circuit conditions 250°C as a against 160°C for PVC Cables and hence have higher short circuit rating.
• Have moisture resistance of nearly 100 times that of PVC.
• Have very high insulation resistance compared to PVC (as high as 1000 times).
• Have high corrosion resistance in polluted atmosphere as compared to PVC Cables.
• Have better properties of resistance to chemical and corrosive gases.
• Have low installation cost because of light weight, dimensions and are far more flexible.
• Have better properties to withstand vibration, hot impacts.
• Have easier & quicker jointing.
• And are ideal for transmission and distribution of power.
