GFLZZ0224-10 HIGH PRECISION 0.2S MEDIUM VOLTAGE 11KV RESIN CAST INDOOR CURRENT TRANSFORMER
INTRODUCE
This model GFLZZ0224-10 dry type indoor current transformer is used in 12KV, 11KV, 10KV, 6KV and 3kV power system, for measuring and protection. It has been used in indoor pole mounted and transmission line. This product has the characteristics of high efficiency and large capacity, and can be customized according to customer requirements. This model current transformer with secondary 1A and 5A output.
For insulation and protection, the assembly is cast in hydrophobic cycloaliphatic epoxy (HCEP) using automatic vacuum pressure. The HCEP material offers superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength. Primary and secondary use pure electrolytic copper, both winding and core have high voltage shielding processing. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet, humid, or polluted environments.
It can be used for less than 12KV distribution cabinet, coal mine, power plant, rail way, factories... .
All of our GFUVE current transformers are strictly comply IEC60044-1, IEC 61869-2, ANSI/IEEE C57.13, GB1208-2006, GB/T 20840.1-2010, GB/T 20840.2-2014, GB/T 22071.1-2018, IEC/EN61010-2-032, IEC/EN 61010-2-031.
