High Voltage Capacitors

HT unit: Capacitor units are manufactured in the range of 50KVAr to 1000KVAr & in the voltage range of 1 KV to 22KV. High voltage capacitor banks (3.3Kv to 132KV / 220KV) are formed by series parallel combinations of these units & connected in various formations of star / double star and delta, depending upon customer’s requirement / applications and applicable protection schemes. We have supplied hundreds of banks of ratings varying between 2-24 MVAr With similar capacitor units. Capacitors are type tested as per IEC / ISS (IS-13925) in CRPI (Govt of India), accredited by NABL Laboratory.
