Iron core na-eji advanced cold-rolled silicon steel sheet. High voltage outgoing line of primary winding enweghị mgbe ahụ n'okpuru nke aha; outgoing line of secondary winding enweghị mgbe ahụ n'akụkụ transverse side nke aha.

Nkọwa dị Mma

• Epoxy Resin Fully Enclosed Cast Insulation：Na-eji advanced vacuum epoxy resin casting technology, o nwere ike ibe fully sealed insulation system na IP65 protection rating. Structure a bụrụ na eto electrical insulation properties dị mfe maka high-voltage surges, na-enye stable operation n'aka normal ma ọ bụ transient overvoltage conditions, ka o bụrụ na-enye efu dust, moisture, na salt fog. O na-enwe ike ime n'ụlọ wet coastal areas na high salinity ma ọ bụ dusty industrial environments, na-enye mmadụ aka na-eji maintenance. Design na-eji maintenance-free na-enye reduce operational costs, minimize downtime for servicing, na enhance overall efficiency of power systems.
• Wide Temperature Range Stability：Na extended operating temperature range of -40°C to +70°C, o na-enye consistent performance n'aka extreme climates. High-quality temperature-resistant insulation materials na-enyere optimal electrical properties n'aka frigid ma ọ bụ scorching conditions, preventing insulation aging caused by temperature fluctuations na-enye long-term stability. Extensive field testing na practical applications confirm service life exceeding 30 years, reducing equipment replacement frequency na long-term costs, na-enye reliable, durable support for power system infrastructure.
• Anti-Fouling Flashover & High Insulation Design：Featuring an external insulation creepage distance ≥31mm/kV na equipped with anti-fouling flashover skirts na hydrophobic coatings, o bụ specifically designed for Class III pollution areas. Features a bụrụ na-enye reduce risk of flashover caused by contaminant accumulation na moisture. Insulation performance tests demonstrate partial discharge ≤5pC na compliance with 12kV/42kV/75kV power frequency/impulse withstand voltage tests, na-enye comprehensive insulation reliability na safe operation n'aka complex conditions.

Nkọwa Technical Parameter

• Rated primary voltage: 20/√3 ma ọ bụ 15/√3 etc.
• Technical standard accords with IEC 60044-2:2003 Part2 Instrument transformers-Part2: inductive voltage transformers

Remarks: Upon request we are glad to offer transformers according to other standards or with non-standard technical specs.
