    Product Details

    Product Functions

    This unit serves two primary functions in electrical distribution networks. Its core role is precise electrical energy metering, facilitated by built-in current and voltage transformers with high accuracy classes (0.2s and 0.2, respectively). It provides critical circuit protection. It is designed for direct compatibility with protective switches like the ZW32 vacuum circuit breaker, allowing it to function as a key node for fault interruption and system safety, effectively merging metering and switching duties.

    Applicable Environment

    Engineered explicitly for outdoor installations on 10kV overhead lines or at the pole-mounted terminals of distribution networks. Its construction ensures reliable operation in harsh weather conditions, including rain, humidity, wide temperature fluctuations, and polluted atmospheres. It is an ideal choice for rural electrification, grid expansions, or any application requiring durable and accurate line-mounted metering and protection.

    Product Highlights
    • Dual-Design Versatility: Offers a standard version combining epoxy casting with a stainless steel enclosure, plus a fully integrated outdoor epoxy resin-cast type for maximum environmental resistance.
    • High Precision & Compliance: Features accurate rated voltage (10/0.1/0.22kV) and a wide adjustable current ratio (10–600/5A), meeting stringent 0.2 accuracy class. Manufactured in full compliance with the GB/T 20840.1.2.3 standard.
    • Rugged & Maintenance-Friendly Construction: The stainless steel shell provides superior mechanical strength and corrosion resistance, while the dry-type, epoxy-cast design eliminates fire risks and requires minimal maintenance.
    • Compact, Integrated Solution: Combines CTs, PTs, and a protective switch compartment into one compact unit, drastically reducing installation space, time, and overall system cost compared to separate components.
    • Ready for Grid Modernization: Its compatibility with standard circuit breakers like the ZW32 makes it a future-proof building block for smart grid and distribution automation projects.
    Frequently Asked Questions
    Q What are the two primary functions of this unit in electrical distribution networks?
