Product Description

The 15-18 KV Surge Arrestors are protection devices which helps to protect transformer against natural lightning & switching surges in a high voltage system. Owing to our advanced technology and innovative machinery, we are able to manufacture and supply these arrestors. They are used in critical atmospheric conditions of high/low temperatures & humidity. We have used Gap less Metal oxide technology which improves VA curves & increased through current capability at over voltages. Further, the 15-18 KV Surge Arrestor is tested at Central Power Research Institute as per IEC 60099 – 4 for all test including pollution (tracking & corrosion) test as per IEC 61109 for 1000 hrs.

Features:
  • It has a non-linear Zinc oxide discs also called Varistor capable of withstanding the surges.
  • They are housed in non-porous Porcelain or Silicone rubber housing with circuitry duly sealed.
  • The arrestor passes entire energy to earth by posing a very low resistance & instantaneously recovers to its original insulation property after passage of surge.
  • The arrestor is comparatively light weight & UN-breakable, hydro phobic, resistant to UV rays, chemicals, ozone & corona. 
  • It is resistant to ageing under climatic conditions, electrical stresses & exhibits non-combustible properties.
  • The optional disconnecter can also be supplied which helps to disconnect ground lead from arrestor to avoid supply interruption & violent shattering of arrestor.
