Description
Product Overview
Our Cast Insulated Pillar Type Current Transformer is a high-reliability electrical component specifically engineered for 50Hz, 10KV power lines. It is mainly used for current and energy measurement, as well as relay protection in medium-voltage power systems. Adopting advanced epoxy resin casting technology, the transformer features a robust structure, excellent insulation performance, and strong vibration resistance, making it an ideal choice for global power grid operators, contractors, and bulk procurement projects.
Product Structure
The transformer is designed with a compact and durable structure, optimized for easy installation and long-term stable operation:
-
Both the primary winding and secondary winding are formed by epoxy resin casting, ensuring superior insulation performance, moisture resistance, and corrosion resistance.
-
The iron core is mounted on the insulating casting body by clips, which are equipped with a nameplate for easy product identification and parameter checking.
-
The base of the clip is provided with four mounting holes, facilitating quick and stable installation on various power equipment or brackets.
