Overview of zj-12kv post insulator

The insulator is formed by vacuum casting of epoxy tree branch, which has good insulation effect. It is mainly used on 12kV switch cabinet, and its size is Φ 85 × 140 (145) mm. For products with special requirements, specifications and dimensions that need to be improved, they can be designed and manufactured according to the user's requirements.
