Detailed Product Description

LA-10 is 1-sealed structure with castingresin insulation and full-sealed indoor installation product. Castingresin insulation can be used to measure current and electronic energy, and relay protection at frequency of 50Hz and voltage of 10kV below. The current transformer is of two types: semi-sealed structure with 200A below and full-sliced double castingresin insulation structure with over 300A.

The semi-concealed castingresin insulation product is of folded-sliced double ring core with primary winding and secondary winding. The resin is casted between the two winding wives. The secondary winding and core are insulated by glass board with core exposed.

The full-sealed castingresin insulation product is of an annealed ting core wound with secondary winding. The primary and the secondary are casted with the core as a whole body insulation casting body.
