Thanks for the East-south Asia customer's trust and support.
The customer wanted to replace the old contact box and fixed contact of 24kV indoor vacuum circuit breaker. When we know clearly the customer's requirement, we provide the drawings for contact box and fixed contact to confirm by the customer.
After got his confirmation and checked the shipping cost, we offer the reasonable price for the customer. He compared with other supplier's price and service a few days, finally he choosed us.
Now, let me introduce the main product contact box.
Products Description
The 24kV contact box is an insulating component molded by epoxy resin APG pressure gel molding process. It is mainly used in trolley-type switchgear and undertakes the functions of electrical connection and insulation isolation.It is applicable to high-voltage switchgear systems with a rated voltage of 24kV and a current range of 630A to 4000A.
