The 35kV isolation switchgear is an essential component in modern power distribution networks, especially in 10kV cable network renovation projects, solving the issue of branch connections in traditional overhead lines. With its fully insulated and sealed design, this equipment significantly reduces the frequency of electrical faults and provides a safer, more reliable power supply solution. The switchgear uses SF6 gas as the insulating medium, ensuring stable long-term operation. It is compact, easy to install, and can operate reliably in harsh environments, widely used in commercial centers, industrial parks, and urban densely populated areas.
The 35kV isolation switchgear is designed with flexible connection methods, supporting ring main unit functions, and can replace a ring main unit when needed. The equipment features excellent protection, with an SF6 gas leakage rate of less than 0.25‰ per year, and is equipped with a gas pressure gauge for real-time monitoring, ensuring the gas pressure remains within the normal range. It is suitable for various complex environments and also features automation capabilities, enabling smart management of the distribution network. With a lifespan of up to 20 years and maintenance-free operation, it reduces maintenance costs.
Utilizes our company’s SF₆ fully insulated, fully sealed modules with a maintenance‑free design.
Fully insulated, fully sealed structure with touch‑safe design; reliable and maintenance‑free, compact and lightweight with a tight configuration; easy installation and operation; suitable for all harsh environments and moisture‑proof; SF₆ chamber protection rated IP65.
Small size for easy installation and operation.
Powder‑coating processes and procedures meet international standards and provide corrosion resistance.
Uses non‑toxic, odorless, high‑dielectric‑strength SF₆ gas as the insulating medium. Busbars, connectors, and load switches are all housed within the SF₆ chamber, achieving a truly outdoor, fully insulated, fully sealed design. SF₆ annual leakage rate is below 0.25 ‰. A pressure gauge mounted on the enclosure allows for real‑time monitoring, and pressure data can be transmitted via RTU to the control center.
Connections employ fully insulated, touch‑safe cable heads, offering safe and flexible cable wiring.
Ring‑network cabinets include comprehensive anti‑misoperation features.
Supports distribution network automation.
Service life: 20 years, maintenance‑free.
