Industry Pain Points and Company Solutions
- In outdoor substations and transmission lines of power systems, polluted environments (such as coastal areas, industrial zones, and saline-alkali lands) often cause increased leakage current on insulator surfaces, leading to pollution flashover accidents that seriously threaten grid safety. Traditional porcelain insulators are heavy, fragile, and have poor hydrophobicity; they also require regular cleaning and maintenance, resulting in extremely high labor and power outage costs.
- Hejian Haokang Electric Co., Ltd. has long focused on the field of electrical insulation. In response to the above pain points, it has launched the outdoor composite insulator - insulating post - 110kV - anti-pollution - integral injection molding product. This product adopts an integrated injection molding process of silicone rubber sheds and FRP core rod, fundamentally eliminating interface gaps and greatly improving moisture resistance and anti-pollution performance. At the same time, it retains the advantages of composite materials such as light weight, high strength, and impact resistance. Our company has rich customization experience and can adjust the structural height, creepage distance, and end fitting connection methods according to customers' actual working conditions, providing full-process support from design to production.
Working Mechanism and Technical Features
- Integral injection molding process: The silicone rubber material and FRP core rod are injection molded in one shot under high temperature and high pressure. There is no bonding interface between the shed and the core rod, preventing moisture and contaminants from entering the interior, and maintaining stable hydrophobicity during long-term operation.
- Anti-pollution design: An alternating structure of large and small sheds is adopted, increasing the creepage distance to 3150mm and optimizing the shed inclination angle to reduce pollution accumulation and increase pollution flashover voltage. The product has passed strict tracking and erosion resistance tests.
- High mechanical strength: The core rod is made of high-strength epoxy FRP, with a rated mechanical load of up to 70kN or more, meeting various working conditions of 110kV posts (such as conductor tension, wind pressure, and seismic action).
- Lightweight: The overall weight is only about 1/3 of that of porcelain posts of the same class, making it easy to transport, install, and replace, and reducing construction costs.
- Maintenance-free: The silicone rubber surface has excellent hydrophobicity migration. Under natural rainwater washing, the pollution layer is not easy to form a continuous water film. No regular cleaning is required, significantly reducing operation and maintenance workload.

FAQ (Frequently Asked Questions)
-
Question: Compared with porcelain insulators, what is the service life of composite insulators?
Answer: Under normal outdoor conditions, high-quality silicone rubber composite insulators can have a service life of more than 20 years. Our products are manufactured by integral injection molding, which eliminates the risk of interface aging, and the silicone rubber formula is optimized for weather resistance, providing stable performance under UV, ozone, and pollution environments. However, regular visual inspections (e.g., checking whether the sheds are cracked or the core rod is exposed) are recommended to extend service life. -
Question: How is the required creepage distance determined?
Answer: The creepage distance should be selected according to the pollution level at the installation site (refer to GB/T 26218 or relevant standards). Generally, for pollution level II, it is recommended to be no less than 2750mm; for level III, no less than 3150mm. More severe pollution requires a higher creepage distance. Our company can recommend suitable specifications based on the pollution level or site photos you provide, and also offer customization services. -
Question: What is the difference between integral injection molding and sectional injection or bonding processes?
Answer: Integral injection molding vulcanizes the sheds and the core rod in a single molding process, forming an integrated structure without interfaces. This provides the best sealing performance, preventing moisture and contaminants from penetrating at the shed roots. In contrast, sectional or bonding processes have bonding interfaces, which are prone to interface degradation and even core rod corrosion after long-term operation. Integral injection is the mainstream process for high-end composite insulators, significantly improving long-term reliability. -
Question: Can this insulator be used in DC systems?
Answer: This product is conventionally designed for AC, but it can be adapted for DC applications by adjusting the shed shape and material formula. DC insulators require higher resistance to tracking and erosion on the sheds. If you have DC requirements, please provide the voltage level and operating environment, and we can evaluate and provide a dedicated design solution. -
Question: Can the end fittings match imported disconnectors or circuit breakers?
Answer: Yes. Our company supports customization of end interfaces. We can machine ball sockets, ball heads, flanges, bolt holes, etc., according to international standards (such as IEC) or customer-specified dimensions. Please provide detailed drawings or physical samples of the connection parts, and we can machine them to match, ensuring installation interchangeability.
Answer: Our products are designed and manufactured in accordance with relevant national standards and IEC standards. Routine type tests include: power frequency dry/wet withstand, lightning impulse withstand, mechanical load, thermo-mechanical performance, tracking and erosion resistance, hydrophobicity test, etc. Specific test items can be carried out by third-party testing organizations according to customer requirements, and reports can be provided.
Answer: Although composite insulators are lightweight, their sheds and core rods still need to be protected from scratches by sharp objects. Our company uses independent foam supports plus corrugated carton or wooden case packaging. Each insulator is individually fixed and marked with a "Fragile" label. For bulk shipments, additional outer protection can be added according to customer requirements to ensure the products arrive at the site intact.
