Cables lab has facilities to undertake type testing of all types of power cables of rating 1.1 kV up to 220 kV voltage rating and power cable accessories as per Indian and International standards. In addition to electrical and physical tests on power cables, the laboratory has state of art test facilities to evaluating cables and materials for flame and smoke characteristics.
Electric cables are designed to carry power and communications for long distances and can act as pathway along which fire can travel and spread. In addition, there are cable installations where large number of cables are installed vertically. These can act as an area of significant fire hazard because of the medium of high fuel loading represented by the insulating and sheathing materials. Fires involving these cables may cause the loss of life as well as damage to the facilities and equipment. In order to avoid such disasters the demand has arisen for improved flame-retardant cables to reduce not only flame propagation but also smoke and toxic emission.
The Flame retardant low smoke cables laboratory carryout fire reaction tests on electric cables and all polymeric materials according to various national and International standards.
Cables laboratory has recently augmented the facilities to take up prequalification test on power cables and accessories of rating up to 400 kV rating, for evaluation of EHV cable system for their long term performance as per IEC 62067.
The test facility has been accredited for Electrical testing as per ISO/IEC 17025 by National Accreditation Board for Testing and Calibration Laboratories (NABL) Govt of India. Cables Laboratory has also accreditation from BIS, DEWA, & ASTA for carrying out tests on cables and accessories.
