Huixing Zhongdian (Beijing) Electric Co., Ltd. manufactures high-quality power fittings, vital components for power transmission and distribution systems. Our products span 10 kV–220 kV voltage levels, supporting overhead transmission lines, substation connections, grid upgrades, renewable energy power stations, and industrial power distribution. As essential elements for fastening, conducting, and protecting electrical infrastructure, our power fittings directly impact system safety, reliability, and service life.
Our comprehensive product portfolio falls into two major categories: transmission line fittings and substation fittings, including suspension clamps, tension clamps, splicing fittings, connecting fittings, hardware for transmission towers and poles, vibration dampers, equipment clamps, busbar fittings, flexible connectors, and grounding materials. All products meet engineering requirements for 10 kV, 35 kV, 110 kV, and 220 kV power systems.
Specially developed for installation of overhead conductors and ground wires, our line fittings are ideal for the following scenarios:
Construction and renovation of urban and rural high-voltage transmission lines
Outlet lines of solar and wind power farms, capable of resisting extreme temperatures, strong winds, and ice accumulation
Coastal, mountainous and heavily polluted regions that require outstanding corrosion resistance
Grid upgrading projects to replace aging and corroded components
Professionally designed for AIS substations, GIS substations, switchyards and power distribution centers:
Mounting and supporting of busbar systems to guarantee stable current distribution
Connection with circuit breakers, disconnectors, power transformers and instrument transformers
Flexible conductor and lead structures to adapt to thermal expansion
Substation grounding systems featuring low resistance to ensure personnel safety
Modular installation for prefabricated and intelligent substations
Our line fittings are precision forged to endure long-term exposure to wind, vibration, temperature changes and corrosive substances:
High tensile strength to bear conductor tension, wind loads and ice loads
Precisely processed contact surfaces to lower electrical resistance and heat generation
Uniform hot-dip galvanization for excellent anti-corrosion performance
Scientifically designed vibration dampers to reduce conductor fatigue and fracture risks
Standardized dimensions for universal compatibility with various conductors and insulators
Our dedicated substation fittings meet stringent standards for electrical performance and structural stability:
Strict dimensional tolerances for precise fitting and smooth installation
Low-resistance contact design to avoid overheating under high-current operation
Optimized structural design against vibration and thermal deformation
Reliable anti-corrosion treatment suitable for both indoor and outdoor substation environments
Full product lineup to support one-stop procurement for complete substation projects
Fully compliant with national, industry and international IEC standards
Strict Quality Control: All products pass full-range performance tests to eliminate defects and ensure long-term operational reliability
