Product Description
ZW32-12 Deep Fusion Outdoor High Voltage Vacuum Circuit Breaker Series (Capacitive Power Taking)
The ZW32-12 Deep Fusion Outdoor High Voltage Vacuum Circuit Breaker Series (Capacitive Power Taking) can be integrated with box-type cover low-power distribution terminals to accommodate various user demand modes. The switch body can output power supply side voltage signals, load side voltage signals, zero sequence voltage signals (8u), current signals, and zero sequence current signals (4i) according to distribution network requirements. The voltage and current sensor accuracy meets line measurement specifications.
Product Overview
Three-phase AC 50Hz outdoor high-voltage switchgear designed for 10kV electrical power systems in rural and urban power grids. Used for opening and closing load current, overload current, and short circuit current in various applications.

Technical Features
- Comprises three-phase pole, spring operating mechanism, drive system, conducting loop, control unit and housing (carbon steel spray or stainless steel). Features three-phase pole design with miniaturization, full-closed structure and excellent sealing, ideal for cold and wet regions
- Efficient spring operating mechanism (manual or electric) with low-power energy-storage motor and minimal energy consumption. Sealed mechanism box prevents rust and ensures reliable operation
- Pole construction uses imported epoxy resin with silicone rubber coating for high temperature, low temperature, UV and aging resistance
- External two-phase or three-phase protective current transformer enables overcurrent protection, fault current quick-break protection with inrush current, and adjustable protection delay time
- Interphase protection CT and zero-sequence CT integrated structure with intelligent controller enables parameter setting, single-phase grounding protection, three-section protection, reclosing, and fault memory. External power supply PT provides operating power
- Controller includes communication module for data upload, fault feedback and "four-remote" functions to achieve distribution network automation
- Optional isolating knife switch (single or dual sides) with three-phase linkage creates clear isolating distance. Mechanical anti-misoperation interlock ensures safe operation between main switch and isolating switch
