As a professional manufacturer of electrical protection equipment, Jinhua Dika Electrical Equipment Co., Ltd. is dedicated to providing robust solutions for power infrastructure safety. Our High-Voltage 220kV Lightning Arrester is engineered specifically for the critical protection of substations and power grids against lightning strikes and transient overvoltages. With ISO9001 certified production processes and a commitment to quality, we deliver reliable products that ensure the stability and longevity of your electrical systems, supporting our global clientele across diverse markets.

This arrester plays a vital role in safeguarding high-voltage equipment. When a lightning surge enters the system, the arrester provides a low-impedance path to ground, diverting the excessive current and limiting the voltage rise across protected equipment. This prevents insulation failure, equipment damage, and potential system outages.

Key Features and Technical Advantages:

High Voltage Rating: Specifically designed for 220kV applications, making it suitable for major transmission substations and backbone grid nodes.
Advanced Insulation Design: Utilizes either high-grade silicone rubber or porcelain housing, offering excellent weather resistance, mechanical strength, and long-term dielectric stability.
Fast Response and Low Residual Voltage: The internal nonlinear resistor elements respond rapidly to overvoltages, clamping the voltage to a safe level with minimal residual voltage, thus providing effective protection.
Durable Construction: Built to withstand harsh environmental conditions, including UV exposure, pollution, moisture, and wide temperature variations.
Sealed Design: Prevents internal moisture ingress and contamination, ensuring consistent performance over its service life.
Easy Installation and Maintenance: Standard mounting interfaces and clear visual indicators (optional) facilitate straightforward installation and status monitoring.

Frequently Asked Questions (FAQ):

What is the primary function of this 220kV Lightning Arrester?
Its primary function is to protect 220kV power substation equipment, such as transformers and bushings, from damaging overvoltages caused by lightning strikes or switching surges. It limits the voltage to a safe level by providing a path to ground for the surge current.
What are the main differences between silicone rubber and porcelain housings?
Silicone rubber arresters are generally lighter, offer better pollution resistance, and are less prone to cracking from mechanical stress. Porcelain arresters are traditionally very robust and have a long history of use. The choice depends on specific environmental conditions and project preferences.
How do I select the correct nominal discharge current (In) rating?
The selection is based on the lightning activity level and importance of the protected equipment at your site. Higher In ratings (e.g., 10kA) offer greater energy handling capability for areas with severe lightning. We can provide guidance based on your location and system data.
Is this arrester suitable for coastal or highly polluted environments?
Yes, especially models with silicone rubber housing. Their design offers excellent resistance to salt spray, industrial pollution, and moisture, making them suitable for harsh coastal or industrial areas.
What kind of maintenance does this arrester require?
It is designed for minimal maintenance. Periodic visual inspection for physical damage or contamination is recommended. Some models may include an optional leakage current monitor for remote condition assessment.
Can you provide arresters for voltages other than 220kV?
Yes. As a manufacturer, we produce a range of surge arresters for various voltage levels, from medium voltage to extra-high voltage. Custom solutions for specific system voltages are available upon request.
What is the typical delivery time for these products?
Delivery time depends on the order quantity and specific model. Standard models can often be shipped promptly from stock. For large or customized orders, we provide a clear production schedule. Our multiple shipment ports facilitate faster logistics.
Do you provide technical support for installation and integration?
We provide detailed installation manuals and datasheets. For complex projects, further technical consultation regarding placement, grounding, and system integration is available.
