Pinggao Electric successfully developed 800 kV high voltage isolation switch
Pinggao Electric has successfully developed China's first 800 kV high-voltage isolating switch with independent intellectual property rights for the State Grid Corporation. Recently, the device was safely delivered to Yinchuan East Substation in Ningxia, marking a major milestone in the company's technological advancement.
This 800 kV isolating switch is part of Pinggao Electric’s first 750 kV high-voltage isolating switch project supporting the State Grid. According to official reports, following the successful operation of the initial 750 kV project, the State Grid plans to build a 750 kV backbone network in the northwest region. This initiative aims to transmit over 200 million kilowatts of power from western China to the eastern and central regions, significantly enhancing energy distribution efficiency.
Establishing a safe, stable, and reliable ultra-high voltage (UHV) power grid is currently one of the top priorities in China’s national power infrastructure development. The successful deployment of this advanced isolating switch not only demonstrates Pinggao Electric’s strong R&D capabilities but also supports the country’s long-term goals of energy security and sustainable development. With this achievement, the company continues to play a key role in advancing China’s smart grid and UHV technology.
Fuel Dispenser Mechanical Accessories
Fuel Dispenser Mechanical Accessories – Classification Overview
Â
Mechanical accessories are the core structural and functional components that ensure the reliable operation, safety, and durability of fuel dispensers. These parts are primarily responsible for fuel delivery, flow control, leak prevention, and physical support. Fuel dispenser mechanical accessories can be classified by function, installation location, material type, and application environment.
Â
1. By Function:
• Fuel Nozzles:
Manual or automatic shut-off nozzles designed for controlled and accurate fuel dispensing.
• Fuel Hoses:
Flexible, pressure-resistant hoses for safe fuel flow between the dispenser and vehicle tank; available in single or vapor-return types.
• Breakaway Couplings:
Safety devices that disconnect in case of excessive tension, preventing fuel spills and equipment damage.
• Swivels:
Allow for flexible nozzle movement, reducing hose wear and improving user convenience.
• Flow Meters:
Measure the volume of fuel dispensed; available in gear, vane, or piston types.
• Filters and Strainers:
Remove impurities from fuel to protect internal components and maintain fuel quality.
Â
2. By Installation Location:
• External Components:
Nozzles, hoses, boots, and breakaways—located on the outside of the dispenser, used directly by the customer.
• Internal Components:
Flow meters, filters, valves, pulleys, and structural brackets—housed within the dispenser body.
• Base and Mounting Parts:
Include foot plates, enclosures, seals, and frames that provide support and structural stability.
Â
3. By Material Type:
• Aluminum Alloy:
Lightweight, corrosion-resistant components for nozzles and housings.
• Stainless Steel:
Durable and suitable for harsh environments, used in valves, filters, and structural supports.
• Rubber and Composite Materials:
Used in hoses, seals, gaskets, and anti-static components for safety and flexibility.
Â
4. By Application Environment:
• Standard Fueling Stations:
General-purpose accessories designed for daily retail use with gasoline or diesel.
• High-Flow or Truck Stations:
Heavy-duty components such as large-diameter hoses and high-capacity nozzles for commercial vehicles.
• Cold or Harsh Climates:
Specially treated accessories with anti-freeze, anti-corrosion, or enhanced sealing features.
Â
All fuel dispenser mechanical accessories are manufactured to meet industry safety standards, ensuring long service life, operational accuracy, and compatibility with international fuel dispenser systems.
