 General
This indoor epoxy resin insulated bushing type current transformer is used in 3.3kV, 6kV, 10kV, 11kV, 12.5kV and 13.8kV power system, for measuring and protection.
It has been used in cubicle switchgear or in bay-installed switching stations.
The current transformer is made from high temperature indoor epoxy resin, amorphous alloy core for metering and high quality CRGO core for protection, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.

Standard
All UNISUN Electric instrument transformers are in conformity with IEC standards, and recommendations IEC 61869. Transformers in conformity with specific country standards can also be supplied. (IEEE C57.13, NBR6855).

Primary Winding:

A high-electrolytic copper primary winding is used, and a silver-base welding material is used at the welding place. Semiconductor shielded paper is wrapped around it to ensure that the partial discharge testing data is qualified.

Secondary Winding

The large-capacity secondary winding is automatically wound with high-insulation, high-purity enameled wire to ensure a wide capacity output under standard accuracy.

Low Cost and Lightweight

By eliminating the need for conductors, insulating oil, and a metal tank, the material and installation costs are significantly lower than those of oil-immersed CTs with equivalent specifications, making it suitable for large-scale deployment in medium- and low-voltage systems.

Maintenance-free and safe

Commonly used in medium- and low-voltage applications, these units are vacuum-poured with epoxy resin or encapsulated in plastic shells. They are oil-free, gas-free, non-flammable, and moisture-resistant, requiring virtually no maintenance and eliminating the risk of oil leaks or fire hazards.

Oil-free, air-free, non-flammable, safe, and environmentally friendly

Epoxy resin vacuum casting: flame-retardant, non-explosive, and with no risk of oil leakage, making it ideal for indoor switchgear rooms and switchgear cabinets.

No contact points, high reliability

The busbar itself is wound in a single loop, eliminating potential issues such as terminal oxidation, loosening, and overheating, resulting in more stable operation.
