High-Quality 35kV Insulators for Substations from China Suppliers and Factory
Product Overview
Designed to meet the rigorous demands of 35kV substations, our insulators serve two core functions: supporting conductors and securing them to pole towers or other substation structures, while strictly confining current flow along the conductor path and preventing leakage to grounded parts.
The store offers transparent round glass insulators with outstanding insulation stability, ideal for power engineering and industrial household lines. We also provide composite insulators featuring glass fiber epoxy resin pull-out rods and silicone rubber sheds. These composite models combine robust mechanical structure with advanced anti-pollution performance, making them a versatile choice for diverse substation working conditions.
Product Performance
⚡ The performance of our 35kV insulators is defined by four key dimensions: electrical properties, mechanical properties, thermal properties, and anti-aging properties, with the following standout advantages:
-
💪High Mechanical StrengthThe glass fiber epoxy resin pull-out rods adopted in composite insulators deliver superior mechanical strength, capable of withstanding various mechanical loads during transmission line operation, and ensuring the stable operation of substation equipment and lines.
-
⚡Excellent Electrical PropertiesComposite insulators exhibit high voltage resistance and low leakage current, effectively preventing electrical faults in 35kV high-voltage systems. The electrical performance also covers core indicators such as flashover characteristics, electrical stability under overvoltages, pollution flashover characteristics, and power frequency breakdown voltage in oil.
-
🛡️Strong Pollution Flashover ResistanceThe silicone rubber sheds of composite insulators have excellent hydrophobicity and pollution flashover resistance. They can maintain reliable insulation performance even under harsh environmental conditions, significantly reducing the risk of substation line failures caused by pollution flashover.
-
🌡️Superior Thermal & Anti-Aging PropertiesOur 35kV insulators are engineered with excellent thermal stability, capable of adapting to temperature changes in substation environments with stable hot and cold resistance. Meanwhile, the durable material composition ensures strong anti-aging performance, extending the service life of the products.
-
🔧Easy Installation & MaintenanceComposite insulators feature a lightweight and simple structure, facilitating quick installation and daily maintenance. Their long service life also helps lower the overall operation and maintenance costs of substations.
Applicable Scenarios
🏭 35kV Substations
As the core application scenario, the insulators are widely used to support busbars, disconnectors, circuit breakers and other key equipment in 35kV substations, realizing the electrical isolation between live parts and grounded structures.
🔌 35kV Overhead Transmission Lines
Matching the voltage level of substations, the insulators can be applied to 35kV overhead transmission lines connected to substations, ensuring the safe transmission of electric energy from substations to end users.
⚙️ Industrial Power Supply Lines
The reliable insulation performance makes the insulators suitable for industrial power supply lines with 35kV voltage level, meeting the power demand of high-power industrial equipment.
🌦️ Harsh Environment Power Systems
Thanks to the strong pollution flashover resistance of composite insulators, they can be used in power systems located in areas with heavy pollution, high humidity or large temperature differences, maintaining stable operation without frequent maintenance.
