The DEWK-12 series outdoor ring main unit is a gas-insulated outdoor ring main unit developed and manufactured by the company. It adopts foreign technologies and is designed based on the characteristics of power distribution networks in various regions of China as well as the actual situation of urban distribution network cabling transformation.
The DFWK-12 series outdoor ring main unit adopts the ZCRM6-12 series SF6 fully sealed and fully insulated ring main switchgear. This switchgear features modularization, expandability, full insulation, full sealing, safety, reliability, and maintenance-free performance. It is suitable for any harsh environment and widely used in industrial parks, residential areas, streets, airports, various buildings, bustling commercial centers and other locations. The standard voltage levels of the DFWK-12 series outdoor ring main unit are 12KV and 24KV, and it can be expanded with distribution network automation functions to realize the intelligentization of the ring main unit, making the power grid stronger and smarter.
Normal Operating Environment
◇ Ambient temperature: Maximum temperature +50℃, minimum temperature -40℃, maximum daily average temperature shall not exceed 35℃;
◇ Relative humidity: Daily average value shall not exceed 95%, monthly average value shall not exceed 90%;
◇ Wind speed: Shall not exceed 35m/s;
◇ Pollution class: Class Ⅲ;
◇ Seismic intensity: Grade 8;
◇ Ground inclination: Shall not be greater than 3 degrees;
◇ Installation location: Installed in places free of fire, explosion, or severe vibration, with good ventilation and no corrosive gases.
Special Conditions
◇ When the equipment is installed at an altitude above 1000 meters, it shall be specially noted to facilitate the company's adjustment of SF6 pressure during manufacturing.
◇ If special harsh conditions are involved, please be sure to consult the company.
Product Features
◆ High Safety
◇ All live parts are enclosed in the SF6 gas tank to achieve full sealing and full insulation;
◇ Equipped with mechanical interlocking that meets the five-prevention requirements, eliminating misoperations;
◇ The incoming and outgoing cables adopt a fully insulated, fully sealed and touchable connection method to maximize personal safety;
◇ A gas pressure monitoring device is installed on the cabinet to realize real-time monitoring of gas pressure during operation;
◇ An explosion-proof pressure relief device is arranged at the rear lower part of the gas tank, which has passed the internal arcing test by an authoritative organization.
◆ Flexible Solutions
◇ Flexible incoming and outgoing line methods, enabling left, right and bottom incoming (outgoing) lines;
◇ Flexible combination methods, allowing arbitrary combination between all units and unrestricted expansion;
◇ Adopting built-in busbar expansion method, fully meeting the requirements of usability, economy and aesthetics;
◇ Flexible design schemes to meet the on-site requirements of users.
◆ Compact and Reasonable Structure
◇ All unit modules have consistent sizes (excluding the metering module), with compact dimensions that do not affect construction convenience.
◆ Economy
◇ Maintenance-free; small footprint and high cost-performance ratio; service life of more than 30 years.
◆ Wide Application
◇ The stainless steel plate of the gas tank part undergoes fully automatic TIG seal welding by robots, with a protection class of IP67. It can be installed in humid, dusty, salty, mining and any air-polluted locations without the need for special preventive measures.
◆ Intelligence
◇ Can be equipped with electric operating devices and power distribution automation terminal equipment to realize intelligent switchgear with "four-remote" functions, meeting all requirements of smart grids for such equipment.
