Environmental Conditions
Parameters (H-GW9-10)
Core Features
- 1. Excellent Outdoor Environmental Adaptability and Anti-Corrosion Capability:
- Technical Detail: Key iron components, such as brackets, bases, and operating rods, undergo hot-dip galvanizationsurface treatment. The hot-dip galvanized coating provides excellent adhesion, wear resistance, and superior electrochemical protection. The porcelain insulators feature a special glazed surface, offering hydrophobicity and anti-pollution flashover capabilities.
- Key Benefit: Ensures that the H-GW9-10 Isolator switch maintains long-term stable electrical and mechanical performance in harsh outdoor environments, including high temperatures, low temperatures, humidity, salt spray, direct UV radiation, and industrial pollution. This significantly extends the equipment’s service life and reduces maintenance costs.
- 2. Highly Reliable Electrical Isolation with Clear Disconnection Point:
- Technical Detail: When opened, the Isolator switch creates a visible air insulation gap, ensuring complete isolation of the equipment from the power source. The contact system uses highly conductive materials and a self-cleaning design to ensure reliable contact and disconnection during opening and closing operations.
- Key Benefit: Provides high-standard electrical isolation assurance, eliminating the risks of live working, and safeguarding the personal safety of maintenance personnel and the safety of downstream equipment during overhaul, in strict compliance with electrical operating procedures.
- 3. Robust Mechanical Structure and Stable Operating Performance:
- Technical Detail: Employs a sturdy frame structure and high-quality components, ensuring the stability and durability of mechanical operation. The operating mechanism is rationally designed for light and reliable opening/closing operations, and can be equipped with manual or motorized operating mechanisms.
- Key Benefit: Guarantees smooth operation of the Isolator switch even under strong winds or freezing conditions, reducing outages caused by mechanical failures and enhancing grid operational reliability.
- 4. Easy Installation and Convenient Maintenance:
- Technical Detail: Features a simple design and standardized structure, facilitating on-site installation and wiring. Porcelain insulators require low maintenance, and the hot-dip galvanized coating significantly reduces the need for routine anti-corrosion coating maintenance.
- Key Benefit: Dramatically shortens installation time and costs, lowers the complexity of daily inspection and maintenance, saving substantial human and material resources for power companies.
- 5. Compliant with International and National Standards:
- Advantage: Product design, manufacturing, and testing strictly adhere to relevant IEC (International Electrotechnical Commission) and GB (Chinese National Standard) standards, ensuring that product performance reaches advanced international levels.
- Transmission and Distribution Lines: Used as isolation protection for line branches, sections, or terminals, facilitating line inspection and fault isolation.
- Outdoor Substations and Distribution Stations: For isolating the high-voltage side of transformers and feeder circuits, coordinating with circuit breakers to enable safe maintenance.
Applications:
- Power Cable Line Terminals: Provide isolation protection at the connection points between cable lines and overhead lines.
- Outdoor Switching Stations: As a component of outdoor switchgear, they achieve power source switching and line isolation.
- Rural Power Grid Modernization: Simplifies the maintenance and management of outdoor lines, enhancing power supply reliability.
- Industrial Parks and Large Mines: Provides reliable electrical isolation in outdoor power distribution areas.
