JDZ16-12R voltage transformer

Product Overview

JDZ16-12R voltage transformer, epoxy resin casting and full enclosed construction, is used indoor for measuring current, electric energy and protective relaying in single-phase or three-phase AC circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 12kV.

Ang produkto may feature ng mataas na reliabilidad, mababang magnetismo ng core, malaking creep distance ng external insulation at maintenance free etc.

Key Features

• Epoxy Resin Fully Enclosed Cast Insulation：Ang JDZ16-12R ay gumagamit ng advanced vacuum epoxy resin casting technology para bumuo ng fully sealed insulation system na may IP65 protection rating. Ang struktura na ito hindi lamang may excellent electrical insulation na kaya ang high-voltage impulses—na nagse-cure ng stable operation sa normal at transient overvoltage conditions—kundi pati na rin ay effectively resists dust, moisture, at salt fog. Ito ay maintains reliable performance sa mga humid coastal areas na may mataas na salinity o dusty industrial environments, na walang need para sa frequent maintenance. Ang maintenance-free design na ito ay significantly reduces O&M costs, minimizes power outage time para sa servicing, at enhances overall power system operational efficiency.
• Wide Temperature Range Stable Operation：May operating temperature range mula -40℃ hanggang +70℃, ito ay ensures stable performance sa extreme climates. Ang high-quality high/low-temperature resistant insulation materials ay prevents insulation aging dahil sa drastic temperature fluctuations, maintaining consistent electrical properties. Ang field tests at long-term applications ay verify service life na lumampas sa 30 years, reducing equipment replacement frequency at long-term costs habang nagbibigay ng reliable support para sa long-term power system stability.
• Anti-Fouling Flashover & High Insulation Design：Ang external insulation ay may creepage distance ≥31mm/kV, equipped with anti-fouling flashover skirts at hydrophobic coatings, making it ideal para sa Class Ⅲ pollution areas. Ang mga disenyo na ito ay significantly reduce ang risk ng flashover dahil sa contaminant accumulation at moisture. Ang insulation performance tests ay show partial discharge ≤5pC, at ito ay passed 12kV/42kV/75kV power frequency/impulse withstand voltage tests, comprehensively ensuring insulation reliability para sa safe operation sa complex conditions.
