  • Product Introduction

    Composite insulators, with their advantages such as lightweight design, strong contamination resistance, and resilience to harsh environmental conditions, are used across multiple sectors of the power system—and particularly excel in challenging operational scenarios. These applications can be broadly categorized as follows:

    I. Transmission Line Sector (Core Application Scenarios)

    High-voltage / Ultra-high-voltage AC and DC lines:
       Suitable for voltage levels of 110kV and above (e.g., ±800kV ultra-high-voltage DC lines), this product can replace traditional porcelain/glass insulators, reducing the load on towers and poles (weighing only 1/3 to 1/5 of conventional products). It helps lower both construction and operation/maintenance costs, making it widely used in inter-regional power transmission and long-distance energy delivery projects.
       Harsh Environment Lines:
            Highly Contaminated Areas: Such as industrial zones (high dust levels), coastal regions (high salt spray), and foggy mountainous areas (prone to condensation). The strong hydrophobic properties of silicone rubber shed covers effectively prevent flashovers caused by contamination.
            Special climate zones—extremely cold regions (below -40°C), high-temperature areas (above 120°C), or areas prone to strong winds and frequent lightning—rely on materials with exceptional temperature resistance, vibration tolerance, and arc-proof capabilities to ensure stable line operation.
       Special Terrain Routes:
       In areas such as mountainous regions, hilly terrains, and routes crossing rivers or streams, the lightweight design makes manual handling and high-altitude installation easier, reducing construction challenges. At the same time, its corrosion-resistant properties ensure durability even in humid, high-moisture environments.


    II. Substations and Distribution Systems

       Equipment insulation within the substation:
        Used for the insulation and fixation of equipment such as busbars, circuit breakers, and disconnect switches—like composite pillar insulators and composite bushing insulators—it can withstand the complex electric field environments found within substations and resists dust accumulation, thereby reducing the frequency of maintenance cleaning.
       Distribution line insulation:
        In 10kV-35kV medium- and low-voltage distribution lines, these are used as insulating supports for conductors on utility poles, making them particularly suitable for urban distribution networks (where space is limited and lightweight, easy-to-install designs are essential) as well as suburban areas with dusty environments (thanks to their excellent resistance to pollution).

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.
