J5463-IS 【 CR type corona resistance superfine glass powder mica tape    (Little glue, moderate glue, glue in more)

 

Standard:   GB/T5019-2002 electrical insulation mica products-test method

            GB/T5020-2002 electrical insulation mica products -definition and general requirement

The technology conditions stipulated J5463-IS corona resistance polyimide film Superfine glass powder mica tape (hereinafter referred to as "mica tape”) the requirements, test method,

Inspection rule, mark, packing, transportation and storage.

The technology conditions is applicable to powder mica paper as base material , double sides respectively With non-alkali glass electrician cloth and CR corona resistance polyimide film for reinforcement Material, by high temperature resistant adhesive and become powder mica tape. This product has even thickness, mica content high, the corona resistance good, and apply to 200 Class asynchronous traction motor, wind generators, oil drilling, frequency conversion motor stator coil key position insulation and other motor, electrical insulation.
