Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Voltage Circuit Isolation: Designed to safely disconnect high-voltage circuits (up to 40.5 kV) for maintenance or fault clearance, ensuring electrical grid and equipment safety.
  • Rated Current Handling: Supports rated currents of 630A and 1250A, enabling reliable operation under heavy load conditions in power distribution systems.

Key features

  • 1. Advanced Material Technology

    • With a 110kV porcelain insulation system and copper contacts, you can achieve enhanced safety margins and low-resistance conductivity, surpassing standard isolators by 25% in voltage protection* [*Disclaimer: Based on internal testing; actual results may vary]. The corrosion-resistant porcelain insulators ensure durability in harsh outdoor environments, while copper contacts minimize energy loss during high-current operations.

  • 2. Ergonomic Interactive Design

    • With an ergonomic handle design, you can ensure safe and precise manual operation even under heavy load conditions. The intuitive mechanical interface allows for reliable disconnection and isolation of high-voltage circuits, reducing operational risks in critical electrical systems.

  • 3. High-Performance Ratings

    • With a rated voltage of 40.5kV and current capacity up to 1250A, you can handle 20% higher capacity than standard isolators* [*Disclaimer: Based on internal testing; actual results may vary]. This makes it ideal for demanding applications requiring robust interruption of high-power circuits in industrial or commercial grids.

  • 4. Commercial-Grade Scenario Solutions

    • Designed for commercial power grids, you can safely isolate high-voltage circuits during maintenance or emergencies, minimizing downtime in industrial settings. Its compact, modular design allows easy integration into existing electrical systems while optimizing space in substations and switchgear enclosures.

  • 5. Certified Safety and Compliance

    • Complying with IEC 62271-102 standards for medium-voltage switchgear, you can meet rigorous safety and performance requirements. The device also adheres to eco-friendly material standards, ensuring minimal environmental impact during manufacturing and operation.

Supplier's note

  1. Technical Breakthroughs:

    • Porcelain Insulation (110kV): Outperforms industry-standard 72.5kV insulation, enabling safer operation in extreme weather.
    • Copper Contacts: Reduces contact resistance by 20% compared to aluminum, minimizing energy loss.
    • Scalable Current Ratings: Dual 630A/1250A options eliminate the need for multiple switch types in mixed-grid systems.

  2. Version Selection Guide:

    • Base Model (630A): Ideal for small substations or residential grids where space and cost are priorities.
    • Advanced Model (1250A): Suitable for industrial plants requiring higher current handling without premium insulation.
    • Pro Model (110kV): Best for high-risk environments like offshore platforms or mountainous regions, where extreme voltage spikes demand reinforced insulation.

With 110kV insulation, you can safely isolate circuits during lightning surges. The Pro model’s 3,000-cycle lifespan exceeds industry benchmarks by 50%, reducing downtime in heavy-use scenarios.
