HDA-40
Manufactured by IEC 99-4 standard.
The internal part of the arrester structure, consisting of metal oxide varistors and glass fiber-reinforced composite material, is enclosed in a high-voltage polymer housing. Modern thermal sealing technology ensures that there are no voids inside the limiter and guarantees excellent adhesion and sealing between different surfaces. The finished restrictor is a completely seamless unit.
