JDZX18-12R boluntaryo ng tensyon

Product Overview

JDZX18-12R voltage transformer, epoxy resin casting and full enclosed construction, is used indoor switch cabinet to measure the 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 17.5/24 kV. 

Ang core ng bakal ay gumagamit ng advanced cold-rolled silicon steel sheet. Ang high voltage outgoing line ng primary winding ay inilabas mula sa itaas ng produkto; ang outgoing line ng secondary winding ay inilabas mula sa transverse side ng produkto.

Key Features

•  Epoxy Resin Fully Enclosed Cast Insulation：Gumagamit ng advanced vacuum epoxy resin casting technology, naglilikha ito ng fully sealed insulation system na may IP65 protection rating. Ang struktura na ito hindi lamang mayroong excellent electrical insulation properties upang makapagsuporta sa high-voltage surges, tiyak na operasyon sa normal at transient overvoltage conditions, kundi pati na rin ang effective resistance sa dust, moisture, at salt fog. Nakakapag-operate ito nang maayos sa mga mapaglalamong coastal areas na may mataas na salinity o dusty industrial environments, walang pangkaraniwang maintenance. Ang maintenance-free design na ito ay significantly reduces operational costs, minimizes downtime para sa servicing, at enhances ang overall efficiency ng power systems.
• Wide Temperature Range Stability：May extended operating temperature range mula -40°C hanggang +70°C, ito ay tiyakin ang consistent performance sa extreme climates. Ang high-quality temperature-resistant insulation materials ay nakakapanatili ng optimal electrical properties sa both frigid at scorching conditions, preventing insulation aging dahil sa temperature fluctuations at ensuring long-term stability. Extensive field testing at practical applications confirm na ang service life ay lumampas sa 30 years, reducing equipment replacement frequency at long-term costs habang nagbibigay ng reliable, durable support para sa power system infrastructure.
• Anti-Fouling Flashover & High Insulation Design：Naglalaman ng external insulation creepage distance ≥31mm/kV at equipped na may anti-fouling flashover skirts at hydrophobic coatings, ito ay specifically designed para sa Class III pollution areas. Ang mga features na ito ay significantly reduce ang risk ng flashover dahil sa contaminant accumulation at moisture. Ang insulation performance tests ay ipinapakita na partial discharge ≤5pC at compliant sa 12kV/42kV/75kV power frequency/impulse withstand voltage tests, ensuring comprehensive insulation reliability at safe operation sa complex conditions.
