Asiatic electrical & switchgear pvt. Ltd. Is engaged in the manufacture and sale of low & high voltage distribution equipment. This company is iso 9001:2000 certified. Surge arrestors are used to protect a transformer against natural lightning & switching surges in a high voltage system. Asiatic offers the gap less metal oxide technology provides superior va curves & increased through current capability at over voltages. The following are its key design features:
1. heart center of the surge arrestor is a non-linear zinc oxide disc also called varistor which is capable of withstanding the surges.
2. housed in non-porous porcelain or silicone
Rubber housing along with other circuitry duly sealed.
3. robust sturdy design in porcelain housing with top aluminum casted cap & bottom copper cap which completely seals the mechanism inside.
4. surge arrestor in silicone rubber is comparatively light weight & un-breakable, hydrophobic, resistant to uv rays, chemicals, ozone & corona.
5. offers resistance to aging under climatic conditions, electrical stresses & exhibits non-combustible properties.
6. can withstand rough handling or shipping.
7. both porcelain & silicone rubber arrestors can be supplied with mounting brackets.
8. flexible, thin sheds in silicone rubber achieve high creepage distances in shorter housing.
9. optional disconnector avoids supply interruption & violent shattering of arrestor.
