25kv composite insulators for railways

Features of 25kv composite insulators for railways
The use of polymeric/silicone rubber base insulators have several advantages over the conventional ceramic insulators eg: light weight, unbreakable, hydrophobic, resistant to ozone & UV radiations, resistant to earthquake shocks, self-cleaning properties & resistant vandalism.
Manufactured to IEC 61109 & ANSI C29.9 specifications
The external sheds are molded from silicone rubber on the latest state of the art injection moulding machinery. The silicone rubber is produced by Orient power.
The end fittings which are intended to connect to a supporting structure or to a conductor are made up of malleable cat iron and are hot dip galvanized as per international specifications.
The metal end fittings are crimped on microprocessor controlled automatic hydraulic crimping machines.
The creepage distance offered is 1050mm i.e. 20mm/kv suitable for medium polluted areas.
The insulators are available in various types of end fittings like stay arm & braket tube varieties.

The construction features for 25kv composite insulators for railways
The core is the insulating part of the composite insulator and is made up to fiberglass rod and is designed to ensure the necessary mechanical characteristics.
The FRP rod used in the manufacturing of silicone rubber insulators is one of core material which is manufactured by protrusion process using boron free ECR grade glass fiber having required mechanical and electrical characteristics.

25kv composite insulators for railways have the most coveted RDSO certificated from China railways. Orient Power is to carry out routine tests on the insulators as desired by international/national standards like: dry power frequency voltage test, mechanical tensile test, mechanical test, UV weathering rubber tensile test and so on as per IEC 61109 or IEC 60383.
