Product Description

Place of Origin:Wenzhou Zhejiang China

Brand Name: SHENGSU

Model Number: DCD-12-630A

Rated current: 630A

The DCD-12-630A series outdoor high-voltage AC isolating switches are single-phase high-voltage electrical equipment primarily used in three-phase AC power systems with a voltage below 12kV and a frequency of 50Hz. These switches are designed to switch circuits under no-load conditions and provide electrical isolation during the maintenance and repair of high-voltage buses, circuit breakers, and other electrical equipment.
The isolating switch consists of a base (which may include a hot-dip galvanized chassis or stainless steel chassis), porcelain insulators or silicone rubber insulators, and conductive components. The structure is designed with good anti-pollution capabilities and corrosion resistance, making it suitable for outdoor use in harsh environments. The device features a self-locking function, ensuring reliable operation. All standard parts are made of stainless steel to enhance durability and oxidation resistance.
