  Salient features The design concept for hollow porcelains depends on the complete design of electrical equipment viz. circuit breakers (SF6, air-blast, air-blast or minimum oil), instrument transformers, condenser bushing or lightning arresters. The design is finalized in consultation & close coordination with the equipment manufacturers so as to achieve desired electrical and mechanical requirements, and comply with dimensional tolerances as per Indian and international standards
