Composite Insulator
The Yfpower Composite Insulator is a silicone rubber and fiberglass-based electrical component engineered for high-voltage transmission and distribution systems, including substations and overhead lines. The insulator’s core rod is typically fiberglass-reinforced polymer, while the housing and sheds are silicone rubber, offering hydrophobic properties that resist contamination from dirt, salt, and ice. This design ensures stable performance in polluted or coastal environments where traditional porcelain insulators may fail.
Composite insulators from Yfpower are built to meet typical industry standards for mechanical strength, creepage distance, and UV resistance, with a standard operating temperature range of -40°C to +50°C. The silicone rubber housing provides a high leakage distance to prevent flashover, while the fiberglass core delivers tensile strength typically rated between 70 kN and 400 kN, depending on the voltage class. These insulators are also lighter than ceramic alternatives, reducing structural load on towers and poles.
Primary buyers include utilities, power transmission companies, and industrial plants requiring reliable insulation for 66 kV to 800 kV systems. Sourcing terms such as MOQ, packaging, and lead time should be confirmed directly with Yfpower, as these are not specified in the listing. The insulator’s resistance to tracking and erosion makes it suitable for regions with high pollution or extreme weather, where consistent performance is critical.
| Core Material | Fiberglass-reinforced polymer (FRP) |
| Housing Material | Silicone rubber |
| Typical Tensile Strength | 70 kN to 400 kN (voltage-class dependent) |
| Operating Temperature Range | -40°C to +50°C (standard) |
| Creepage Distance | Customizable; typical 20 mm/kV to 30 mm/kV for high pollution areas |
| Leakage Distance | Designed to exceed standard requirements for pollution resistance |
| UV Resistance | High; silicone rubber formulation resists degradation |
| Hydrophobicity | Self-cleaning surface reduces contamination buildup |
| Typical Voltage Class | 66 kV to 800 kV |
| Weight | Typically 50% lighter than equivalent porcelain insulators |
Yfpower operates from Dongguan, Guangdong, with a listed address at No.10 Longxi Road, Nan Cheng Street.

Sourcing Composite Insulator from Yfpower - Japan Import Guide
Before ordering, verify the insulator’s voltage class compatibility with your system, as Yfpower offers solutions from 66 kV to 800 kV. Confirm the mechanical tensile strength rating to ensure it meets your line’s mechanical load requirements, particularly in regions with high wind or ice loads. Request documentation for the fiberglass core and silicone rubber housing to validate material quality and compliance with industry standards.
Logistics details such as lead time, packaging, and Incoterms must be clarified directly with Yfpower, as these are not specified in the listing. Composite insulators are typically shipped in protective crates to prevent damage to the silicone sheds during transit. Buyers should also confirm whether the supplier provides installation guidance or accessories like end fittings, which are critical for proper mounting.
Quality checks should include visual inspections for defects in the silicone housing and fiberglass core, as well as dimensional verification to ensure the insulator matches the ordered specifications. Request third-party test reports for electrical and mechanical performance, including creepage distance, tensile strength, and pollution resistance. For high-value orders, consider on-site inspection or witness testing during production to ensure compliance with your technical requirements.
