RAILWAYS INSULATORS

Insulators for railway traction applications are a category apart from the regular insulators as they demand extremely stringent performance and safety requirements. Modern insulators has set the standards in the design, manufacture, testing and supply of insulators for railway traction application. We manufacture various categories of 25kV railway insulators addressing every need for the electrification of railway lines.
Following types of insulators are being manufactured by Modern insulators for railway applications:

  •  Stay arm insulators
  •  Bracket insulators
  •  9 Tonne insulators
  •  Sectioning insulators
  •  Post insulators and
  •  Operating rod insulators

The insulators are manufactured to not only meet but exceed the demands laid out by the RDSO, the governing body for electric traction insulator applications. The insulators manufactured are subjected to routine and acceptance tests in line with the RDSO standards. The sample size is greatly increased to prove the consistency in product performance.
These insulators apart from being subjected to regular tests are also subjected to tests like

  •  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 stringent control of manufacturing process and strict adherence to quality control has made Modern railway insulators stand apart from the competition. Modern continues to hold a reputation of being the single largest supplier of insulators for railway application in India. Modern Insulators supplies about 70% of the Indian Railway’s needs.

Our Other Products

HOLLOW
INSULATORS

The hollow porcelain insulators are manufactured using high strength Aluminous porcelain and subjected to strict process and dimensional controls.This insulators protect the internal components from being exposed to the vagaries of the weather

SOLID CORE POST
INSULATORS

Modern’s Solidcore insulators are not only designed to meet the essential mechanical & electrical properties but also to effectively meet the loads arising out of short circuit, seismic, wind, thermal, ice and any other dynamic loads.

LONGROD
INSULATORS

The long rod insulators are subjected to static and dynamic loads including wind load, ice load, conductor galloping, short circuit forces etc. and are designed to withstand such loads constantly and continuously for decades.
