Product introduction
The JDZX935A is a high-precision, resin-cast voltage transformer designed for medium-voltage power systems. It provides accurate voltage transformation for metering, protection, and monitoring applications in 10kV-35kV distribution networks.
Key Features
✔ High Accuracy
·Measurement:Class 0.2, 0.5 (IEC 60044-2)
·Protection: Class 3P, 6P (for fault detection)
✔ Robust & Reliable
·Epoxy resin insulation– Excellent dielectric strength, moisture resistance, and mechanical durability
·Dry-type, maintenance-free– No oil or SF6 gas required
✔ Compact & Lightweight
·Space-saving design for easy installation in switchgear, RMUs, and control panels
✔ Wide Compatibility
·Secondary output: 100V, 110V, or custom values
·Supports **standard protection relays and energy meters
✔ Safety Compliance
·Meets IEC 60044-2, GB/T 20840, and ANSI standards
Applications
·Energy metering (substations, industrial plants)
·Protection relaying (over/under-voltage, earth fault)
·SCADA & automation systems
·Renewable energy integration (solar/wind farms)
Product advantage
·Long service life – Resistant to environmental stress
·Customizable – Optional secondary taps, mounting styles
·Cost-effective– Low maintenance, high reliability
