Product Overview
JDZX16-12R 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.
The iron core adopts advanced cold-rolled silicon steel sheet. High voltage outgoing line of primary winding was fetched out from top of the product; outgoing line of secondary winding was fetched out from transverse side of the product.
Key Features
Anti-Fouling Flashover & High Insulation Performance：With external insulation creepage distance ≥31mm/kV, equipped with anti-fouling flashover skirts and hydrophobic coatings, suitable for Class Ⅲ pollution areas. Partial discharge ≤5pC, passing 12kV/42kV/75kV power frequency/impulse withstand voltage tests, effectively reducing the risk of fouling flashover and ensuring long-term reliable operation in harsh environments.
Compact Design & Flexible Installation：Volume reduced by 40% compared to traditional oil-immersed transformers, weighing only 80kg, supporting vertical or horizontal installation. Compatible with mainstream medium-voltage switchgear like KYN28 and XGN15, simplifying substation layout and saving space costs.
Intelligent Monitoring Interface：Optional Modbus RTU digital output module for real-time voltage data transmission to monitoring systems, supporting remote condition monitoring and fault early warning. Compatible with smart grid architecture to facilitate digital upgrading of substations.
International Standard Compliance：Complies with IEC 60044-2 and GB/T 1207-2022 standards, certified by CE and RoHS. Insulation system meets UL94 V-0 flame retardant grade, with internationally recognized product quality and safety, suitable for domestic and foreign power engineering projects.
