Railway Insulator for traction applications are a category that differs from regular insulators in that they require extremely stringent performance and safety requirements. Modern isolators have set standards in the development, manufacture, testing and delivery of isolators for the use of railway traction. We manufacture various categories of 25 kV Railway Insulator that meet all the requirements for the electrification of railway lines.
The following types of isolators are manufactured by Railway Insulator for railway applications:
- Stay arm insulators
- Bracket insulators
- 9 Tonne insulators
- Sectioning insulators
- Post insulators and
- Operating rod insulators
The Railway Insulator are manufactured to not only meet, but exceed, the requirements of RDSO, the governing body for electrical traction isolator applications. The isolators manufactured are subjected to routine and acceptance tests in accordance with the RDSO standards. The sample size is increased significantly to demonstrate the consistency of product performance.
These isolators are not only subjected to regular tests, but also tests such as
- Flexural strength of test specimen.
- X-Ray Diffraction (XRD) analysis
- Scanning Electron Microscope (SEM) investigation
- Energy Dispersive X-Ray (EDX) Analysis
- Check on Modulus of Elasticity
- Power arc tests
These tests and the strict control of the manufacturing process, as well as strict adherence to quality control, have made Railway Insulator stand out from the competition. We continues to have the reputation of being the largest single supplier of isolators for railway applications in India. We cover about 70% of the Indian Railway’s needs.
