Also, when it comes to rates, our XLPE insulated cables are available at the least prices than any other market. We are one of the major XLPE power cables manufacturers in India. BAJAJ-XR Cross Linked Polyethylene Power Cables (XLPE) Different types of cables in the voltage grade 1.1 to 33 kV are being used today in utilities and industries depending on their mechanical and electrical properti~s on one hand and economy in using them in the other. Among these, paper cables, ever since their introduction have been enjoying undisputed acceptability. However, the advent of XLPE cables in the late 70's marked the beginning of a gradual but steady replacement of paper cables especially for higher voltagE; applications. XLPE cables could command an immediate acceptance resulting from their ease of handling, moisture proof sheathing, easier jointing procedures and ease of maintenance. The XLPE range of cables offered by BAJAJ CABLES is known by its brand name BAJAJ-XR. BAJAJ-XR cables of 6.6 kV to 33 kV grade are manufactured as per Indian Standard 7098 (Part II) of 1985. PROPERTIES AND ADVANTAGES OF BAJAJ-XR CABLES The excellent thermal properties of BAJAJ-XR cables permit maximum continuous conductor operating temperature of 90.C and short circuit temperature of 250.e. Moreover, it has very low dielectric loss which does not vary much over the entire operating temperature range. These characteristics, alongwith the low dielectric constant make BAJAJ-XR cables particularly suitable for high voltage applications. Given below are additional outstanding features. High Continuous Current Rating: Its ability to withstand higher operating temperature of 90.C enables much higher current ratings than those of Pve. High Short Circuit Rating: Maximum allowable conductor temperature during short circuit of 250.C is considerably higher than for PVC cables resulting in greater short circuit withstand capacity. High Emergency Load Capacity: BAJAJ-XR cables can be operated even at 130.C during emergency, therefore in systems where cables are installed in parallel, failure of one of two cables will not bring down the system capacity because the remaining cables can carry the additional load even for longer duration until repairs/replacements are carries out. Low Dielectric Losses: BAJAJ-XR cables have low dielectric loss angle. The dielectric losses are quadratically dependent on the voltage. Moreover, these losses occur continuously in every charged cable whether it carries load or not. Hence use of XLPE cable at higher voltages would result in considerable saving in costs. Charging Currents: The charging current are considerably lower permitting dose setting of protection relays. Easy Laying and Installation: Low weight and small bending radii make laying and installation of cable very easy. The cable requires less supports due to low weight. High Safety: High safety against mechanical damage and vibrations. APPLICATIONS Because of the excellent mechanical and electrical properties BAJAJ-XR cables are being used extensively in all power stations and in industrial plants. They are ideally suited for chemical and fertilizer industries where cables are exposed to chemical corrosion or in heavy industries where severe load fluctuations occur and for systems where there are frequent over voltages. Cables can also be used at higher ambicol temperature on account of their higher operating temperature. Their excellent installation properties permit the cable to be used even under most difficult cable routing conditions and also in cramped conditions e.g. city distribution network. Single core cables due to their excellent installation properties are used in power stations, sub-stations and industrial plants with advantage. CONSTRUCTION BAJAJ-XR cables are manufactured and tested in accordance with 15:7098 (Part II) - 1985. Its salient constructional features are as under: Conductor: The conductors m,ade from electrical purity aluminium wires, are stranded together and compacted. All sizes of conductors of single or three core cables are circular in shape. Conductor construction and testing comply to IS: 8130 - 1984. Installation: High quality BAJAJ-XR (XLPE) unfilled insulating compound of natural colour is used for insulation. Insulation is applied by extrusion process and is chemically cross linked by continuous vulcanization process. Shielding: All BAJAJ-XR cables rated above 3.3 kV are provided with both conductor shielding and insulation shielding. Both conductor and insulation shielding consist of extruded semi-conducting compound. Additionally, insulation is provided with semi-conducting tape and non-magnetic metallic tape screen over the extruded insulation. Conductor shielding XLPE insulation and insulation shielding are all extruded in one operation by a special process. This process ensures perfect bonding of inner and outer shielding with insulation. Inner Sheath (Common Covering): In case of multicore cables, cores are stranded together with suitable non-hygroscopic fillers in the interstices and provided with common covering of plastic tape wrapping. As an alternative to wrapped inner sheath, extruded PVC inner sheath can also be provided. Armouring: Armouring is applied over the inner sheath and normally comprises of flat steel wires (strips) for multicore cables. Alternatively, round steel wire armouring can also be offered. Single core armoured cables are provided with non­ magnetic armour consisting of hard drawn flat or round aluminium wires. Outer Sheath: A tough outer sheath of heat resisting PVC compound is extruded over the armouring in case of armoured cables or over non-magnetic metallic tape covering the insulation or over the non-magnetic metallic part of insulation screening in case of unarmoured single core cables. This is always black in colour for the best resistance to outdoor exposure. The outer sheath is embossed the voltage grade and the year of manufacture. The embossing repeats every 300/350 rnrn along the length of the cable. TESTING AND QUALITY CONTROL BAJAJ-XR cables are manufactured under advanced manufacturing and testing facilities. The cables are type tested and routine tested in accordance with IS 7098. The following tests are carried out as routine tests on every length of cable manufactured:

• Conductor resistance test
• Partial discharge test
• High voltage test
