25kV COMPOSITE INSULATORS FOR RAILWAYS
click on above pictures to view enlarge view !
 
Asiatic manufacturers world class range of 25 kV composite insulators for Railways in 9 Tonne, Stay arm hook & Bracket tube configurations.FEATURES

• 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 earth quake shocks , self deaning properties & resistant to vanda lism. 

• Manufactured to I EC 61109 & RDSO specifications TUSPC/OHE/INSCOM/1070. 

• The external sheds are moulded from Silicone rubber on the latest state of the art injection moulding machinery from Desma Germany. The sthcone rubber is procured from world renowned companies across the world. 
The end fittings which are intended to connect to a supporting structure or to a conductor 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 metal end fittings are crimped on microprocessor controlled automatic hydraulic crimping machines. • The creepage distance offered is 1050 mm i.e. 20 mm/kV suitable for medium polluted areas. The insulators are available in various types of end fittings like 9 tonne, Stay Arm & Bracket tube varieties...


CONSTRUCTION FEATURES 
The core is the insulating part of the composite insulator and is made up of fiber glass 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 haying required mechanical & electrical characteristics. 


DESIGN TESTS 
0ur entire range of 25 kV composite insulators have the most coveted RDSO certification from Indian railways and the entire design tests have been duly witnessed by RDSO engineer at our works. Further, the composite insulators have been extensively type tested as per the IEC/IS/RDSO specifications.  


QUALITY CONTROL 
Asiatic has the requisite infrastructure to carry out routine tests on the insulators as desired by international/national standards like: Dry power frequency voltage test , Mechanical Tensile test, Thermo mechanical test chamber, U.V. weathering Rubber tensile test etc as per IEC 61109.
