25KV Composite Insulators

• The external sheds are moulded from Silicone rubber on the latest state of the art injection moulding machinery from Desma Germany.
• The end fittings are made up of malleable cast iron BM:350 of IS 14329 or SG cast iron conforming to grade 400/151 of IS 1865 iron and are duly Hot dip galvanized to a min of 750-10009/m2as per RDSO specifications.
• The fittings are crimped on microprocessor controlled automatic hydraulic crimping machines. Creepage distance offered is 1050 mm i.e. 20 mm/kV suitable for medium polluted areas.

• The core is made up of fiber glass rod which is a insulating part of the composite insulator which ensures all the necessary mechanical characteristics. The FRP rod is one of core material which is manufactured by protrusion process using boron free ECR grade glass fiber haying required mechanical & electrical characteristics.

• It has RDSO certification from Indian railways. They are also tested duly witnessed by RDSO engineer at our works. Further, the composite insulators have been extensively type tested as per the IEC/IS/RDSO specifications.

• We have all the requisite infrastructure to carry out routine tests on the insulators as per the international/national standards such as Dry power frequency voltage test, Mechanical Tensile test, Thermo mechanical test chamber, U.V. weathering Rubber tensile test etc as per IEC 61109.
