As a professional manufacturer of high-voltage electrical protection equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to offer our Customized 36kV Surge Arrester with Porcelain Housing. Engineered for the rigorous demands of substation environments, this arrester is a cornerstone of reliable power system protection. We understand that every substation has unique requirements, which is why we provide tailored solutions to match specific project needs, ensuring optimal performance and seamless integration into your existing infrastructure. Our commitment to quality, backed by a comprehensive manufacturing and export operation, delivers a product that safeguards your critical assets against transient overvoltages.

This surge arrester is designed to divert dangerous surge currents safely to ground, thereby protecting expensive substation equipment such as transformers, circuit breakers, and switchgear. Its robust construction and advanced design principles make it a trusted choice for utilities and industrial power networks worldwide.

Key Features & Technical Advantages:

High-Performance Porcelain Housing: The porcelain housing provides excellent mechanical strength, superior pollution performance, and long-term stability under harsh environmental conditions. It is resistant to UV radiation and thermal cycling, ensuring durability.
Advanced Valve Block Technology: At the core of the arrester is a high-grade metal oxide varistor (MOV) block. This component offers exceptional non-linear voltage-current characteristics, providing fast response times and high energy absorption capacity.
Customizable Design: We offer a range of customization options to fit your exact specifications:
- Mounting bracket configurations (top-mounted, side-mounted).
- Creepage distance adjustments for specific pollution levels.
- Connection terminal types and sizes.
- Optional pressure relief diaphragm for enhanced safety.
- Specific color coding or labeling as per client request.
Reliable Sealing System: A hermetically sealed design prevents moisture ingress, which is critical for maintaining the internal components' integrity and ensuring a long service life, even in humid or coastal areas.
Comprehensive Protection: Effectively limits switching surges and lightning impulses, maintaining system voltage stability and preventing costly downtime and equipment damage.

Detailed Technical Specifications:

Parameter	Specification
Rated Voltage (Ur)	36 kV
Continuous Operating Voltage (Uc)	29 kV
Nominal Discharge Current (In)	10 kA (8/20 µs)
Line Discharge Class	Class 2 or 3 (Customizable)
Pressure Relief Current (Optional)	Up to 40 kA
Housing Material	High-Alumina Porcelain
Sealing Type	Hermetic Seal
Operating Temperature Range	-40°C to +60°C

Benefits for Your Operation:

Enhanced System Reliability: Minimizes the risk of unexpected failures in transformers and other key assets, leading to improved grid stability.

Frequently Asked Questions (FAQ):

Q: What is the primary function of this 36kV surge arrester?
A: Its primary function is to protect substation equipment from transient overvoltages caused by lightning strikes or switching operations by safely diverting the surge current to ground, thereby limiting the voltage across the protected equipment.
Q: Why is a porcelain housing chosen over polymer?
A: Porcelain offers proven long-term performance, high mechanical strength, excellent resistance to tracking and erosion in polluted environments, and superior stability under wide temperature variations, making it a reliable choice for critical substation applications.
Q: What level of customization do you offer?
A: We offer extensive customization, including mechanical dimensions, mounting arrangements, creepage distance for specific site pollution severity (SPS) levels, terminal types, and the inclusion of optional features like a pressure relief device or specific ratings.
Q: How do I select the correct arrester for my 36kV substation?
A: Selection depends on several factors: system voltage, required protection level, location (indoor/outdoor), pollution level, and seismic conditions. We provide technical support to help you choose the optimal configuration based on your system studies.
Q: What is the expected service life of this arrester?
A: Under normal operating conditions and within specified limits, the expected service life can be several decades. The hermetically sealed porcelain design is key to preventing internal degradation and ensuring longevity.
Q: Do you provide test reports or certifications?
A> Yes, standard routine tests are conducted on every unit. Additional type test reports according to international standards such as IEC 60099-4 are available upon request to support your project qualification process.
Q: What are the main shipping ports and lead time?
A: We ship primarily from Shanghai, Tianjin, Guangzhou, and Ningbo ports. Lead time varies based on the order quantity and customization level; standard configurations typically have shorter lead times.
Q: Can this arrester be used in retrofit projects to replace older units?
A: Absolutely. Our customization capability allows us to design arresters that match the physical and electrical footprint of existing equipment, facilitating straightforward replacement and system upgrades.
