GFJLSZV-35W OUTDOOR COMBINED 33KV THREE PHASE INSTRUMENT CURRENT TRANSFORMER & VOLTAGE TRANSFORMER
INTRODUCE
This model GFJLSZV-35W outdoor combined current transformer and voltage transformer is used in 36KV, 35KV, 34.5KV, 33KV, 27KV, 25KV 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. This model combined CT & VT is suite for 33KV 3P3W or 3P4W power system.
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 36KV distribution line, coal mine, power plant, rail way, factories...
The 33kV combined CT & VT are strictly comply IEC60044-1,2, IEC 61869-1,2,3, IEC60186, ANSI/IEEE C57.13, NBR6855, BS 7729, GB1207-2006, GB/T 20840.3-2013, GB/T 22071.2-2017, GB/T 20840.102-2020. It has been used many substations and wind power plants.
