Looking for Composite Polymer Lightning Arresters in India?
At Venkateswara Suppliers Pvt Ltd (VSPL), we manufacture reliable Polymer Lightning Arresters for 11 KV and 33 KV distribution systems. Designed using zinc oxide (ZnO) varistors, FRP housing, and silicone polymer insulation, our arresters deliver superior protection against voltage surges, lightning strikes, and switching transients — ensuring long-lasting safety for electrical networks.
What Is a Composite Polymer Lightning Arrester?
A Lightning Arrester (LA) protects electrical systems from transient overvoltages caused by lightning or switching surges.
Composite Polymer Lightning Arresters use non-linear zinc oxide blocks encapsulated in a polymer housing to discharge surge energy safely to the ground — without any spark gap.Compared to porcelain arresters, polymer versions are lighter, hydrophobic, and maintenance-free, offering long-term stability even in polluted or coastal zones.
