Composite Insulator

Composite insulators consist of a glass fiber-reinforced plastic (FRP) core rod, silicone rubber or ethylene propylene rubber sheds, and metal end fittings. They represent a multi-layered insulation structure used primarily for electrical insulation in high-voltage transmission lines and substations.

  • Product Introduction

    Composite insulators (also known as synthetic insulators) are high-voltage insulation devices manufactured through an integrated molding process at high temperatures, using a glass-fiber-reinforced core rod, an organic silicone rubber shed, and metal end fittings. Unlike traditional porcelain or glass insulators, which rely on multiple stacked segments, these insulators feature a revolutionary "core rod-shed-rigid fitting" design that combines all three components into one seamless unit, offering the following key advantages:

    1. Lightweight: Weighing only 10%-20% of porcelain insulators, the core rod boasts a tensile strength exceeding 1000 MPa, enabling it to withstand strong winds of up to Grade 8, as well as ice accretion impacts. As a result, single-tower substations on ultra-high-voltage lines can achieve weight reductions of up to 3.2 tons.

    2. Smart, Maintenance-Free Design: The silicone rubber umbrella sheds feature hydrophobic migration properties, achieving a contamination resistance rating of Level IV (compared to just Level II for porcelain insulators), resulting in an 87% reduction in failure rates in coastal areas exposed to salt spray. Additionally, core rod cracks can be detected early as a warning sign, effectively mitigating the risk of glass insulator breakage.

    3. Strong environmental adaptability: Suitable for challenging environments such as high altitudes, intense vibrations, and industrial pollution, effectively addressing the issue of wind-induced vibration-related cable failures in wind farm collection lines.

    4. Long-term Cost-Effectiveness: Designed for a lifespan of 15–20 years, this product continues to require optimization to enhance UV resistance, yet its overall maintenance costs are reduced by more than 60% compared to porcelain insulators.

    Application scenarios: 1000kV ultra-high-voltage projects, coastal power grids, and new-energy grid connection lines. With their "lightweight, high reliability, and environmentally friendly" features, composite insulators have become the preferred choice for high-voltage applications and polluted areas, driving the power grid toward greater intelligence.

FAQ

How can we ensure the safe transportation of products? And how is shipping cost calculated?

We use professional export packaging materials and techniques to provide multi-layered protection for your products, ensuring they arrive safely at their destination. For fragile items, we apply extra reinforcement measures. Shipping costs vary depending on the transportation method you choose—such as sea freight, air freight, or express delivery—as well as the weight, dimensions of the goods, and your specific destination. After you place your order, we’ll calculate the exact shipping fee based on the actual situation and promptly inform you.

What payment methods do you accept?

We accept a variety of secure and convenient payment methods, including wire transfers to our bank account, Western Union, and PayPal. Payment terms typically require a 30% down payment, with the remaining 70% due upon receipt of the bill of lading copy. For customers who maintain long-term, stable partnerships or place large orders, we can discuss more flexible payment arrangements.

How long is the typical order delivery cycle?

Sample orders typically take around 7 business days for delivery. For bulk production orders, shipment will be arranged within 20–30 business days after we receive your 30% deposit and once the product design has been confirmed. In case of special circumstances or if you have urgent requirements, please let us know in advance, and we’ll do our best to coordinate and expedite the process.

Do you have a minimum order quantity requirement?

Yes, for international orders, we do have a minimum order quantity requirement. The specific threshold may vary depending on the product. If you’re looking to purchase in smaller quantities, feel free to reach out—we’ll do our best to work with you and provide a suitable solution.

What is the price of your product?

Our product prices may vary depending on factors such as fluctuations in raw material markets, order quantities, and product specifications. You can reach out to us via website message, email, or phone to share your detailed product requirements, and we’ll promptly send you a new, accurate quotation.
