GFLZZ1235-20A2 15KV 20KV MEDIUM VOLTAGE 5P20 INDOOR HIGH ACCURACY CURRENT TRANSFORMER 0.2S
INTRODUCE
This model GFLZZ1235-20A2 indoor dry type current transformer is used in 15kV, 17.5kV, 20kV, 22kV and 24kV power system, for measuring and protection. It has been used in outdoor pole mounted and transmission line. This product has the characteristics of high efficiency and large capacity, and can be customized according to customer requirements.
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 20KV 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, NBR6855, GB/T20840.1-2010, GB/T 20840.2-2014, GB/T 22071.1-2018, IEC/EN61010-2-032, IEC/EN 61010-2-031.
