  • Product Description

  • Product Introduction

    Glass insulators are core insulation components in power systems, primarily composed of a glass element (the core insulator), a steel cap (for connecting wires), a steel foot (used to secure the insulator to the tower), and an adhesive agent (to bond the components together). They are widely used in high-voltage and ultra-high-voltage AC/DC transmission lines as well as substations, where they provide essential functions such as insulating and supporting conductors, preventing flashovers caused by pollution, and resisting arc formation—thereby ensuring the safe and stable transmission of electricity.
    Product Features

       Reliable insulation: The glass components exhibit excellent insulating performance, meeting the requirements for power-frequency withstand voltage and creepage distance, and retaining their insulating capability even after lightning-induced damage.

      Easy Maintenance: Features a self-destructing zero-value property—when insulation fails, the glass component automatically breaks, allowing for quick detection and replacement.

       Weather-resistant and durable: The surface is smooth, self-cleaning, and resists dirt buildup, slowing down the aging process while maintaining stable electrical and mechanical performance even after prolonged operation.

       High strength: Exhibits strong mechanical resistance to damage (commonly available in capacities like 70 kN, 100 kN, etc.), capable of withstanding both conductor tension and external impacts.

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.
