7S-JDKG 35kV Outdoor SF6 Load Break Switch 630A 20kA

7S-JDKG 35kV outdoor SF6 load break switch, rated current 630A, short-circuit withstand 20kA, IP65 outdoor protection grade. Dual operation: manual insulated rod / optional motorized type. High purity SF6 gas insulation, anti-corrosion & weatherproof for substation and power grid.

7S-JDKG 35kV SF6 outdoor load break switch is gas-insulated medium voltage switchgear designed for high voltage power distribution system. It adopts high-purity SF6 gas as insulating medium, avoiding electric breakdown and guaranteeing long-term stable operation. Integrated epoxy resin insulated bushings with IP65 outdoor protection rating, rainproof, dustproof, anti-aging, suitable for harsh outdoor working environment.

Core structure includes three modules:

  1. Main Module: 35kV three-phase epoxy resin encapsulated SF6 insulated bushings, fully sealed gas chamber and high conductivity conductive circuit.
  2. Operating Module: Support manual insulated rod operation and optional motorized operating mechanism, realize reliable opening and closing.
  3. Auxiliary Components: Standard mounting fasteners, sealing parts and real-time status indicator for easy installation and maintenance.

Key advantages: 
• Fully sealed gas chamber, low SF6 leakage, maintenance-free long time operation
• Built-in anti-misoperation interlock device to prevent wrong operation
• Wide working temperature: -40℃ ~ +65℃, resistant to salt fog and weather aging
• Compliant with IEC 62271-200 & GB 3804 standards

Typical application scenarios:

  • Outdoor branch switch & user service switch for urban and rural power grid
  • 35kV substation feeder circuits
  • Industrial park, mining area, large manufacturing high voltage distribution projects
