As a leading manufacturer in electrical protection, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our Professional 36kV Polymer Housed Surge Arrester. Engineered for demanding environments, this heavy-duty arrester is designed to provide reliable overvoltage protection for critical power transmission and distribution assets. Our commitment to quality, backed by a robust manufacturing process and stringent quality control systems, ensures each unit delivers consistent, high-performance safeguarding against lightning strikes and switching surges. With extensive export experience across global markets, we understand the diverse needs of utilities and industrial clients, making this arrester a trusted component for enhancing grid resilience.

Core Product Features and Technical Advantages:

Advanced Polymer Housing: The silicone rubber or polymer housing offers superior hydrophobicity, excellent pollution resistance, and outstanding UV stability. This design eliminates the risk of external flashover in contaminated or humid conditions and requires minimal maintenance compared to porcelain-housed units.
Heavy-Duty, Station-Class Design: Built to withstand the rigorous electrical and mechanical stresses of substation and transmission line applications. The robust construction ensures high energy handling capability and long-term operational stability.
High-Performance Metal Oxide Varistor (MOV) Blocks: At the heart of the arrester are precisely engineered zinc oxide varistor discs. These provide a highly non-linear voltage-current characteristic, ensuring rapid response to overvoltages and reliable clamping of transient voltages to safe levels.
Superior Sealing and Pressure Relief: Features a hermetically sealed design to prevent moisture ingress, a primary cause of arrester failure. Many models include an integrated pressure relief system that safely vents internal gases in the rare event of a catastrophic failure, protecting surrounding equipment.
Excellent Energy Absorption and Durability: Designed to absorb and dissipate high levels of surge energy repeatedly without degradation. This results in a long service life and reduced total cost of ownership.
Lightweight and Easy Installation: The polymer housing makes the arrester significantly lighter than traditional porcelain types, simplifying handling, transportation, and installation on various structures like poles, gantries, or substation frames.

Key Technical Specifications:

Parameter	Typical Value / Description
Rated System Voltage (Ur)	36 kV
Continuous Operating Voltage (Uc)	As per IEC/ANSI standards for 36kV systems
Nominal Discharge Current (In)	10 kA or 20 kA (standard options)
Lightning Impulse Residual Voltage	Specified per model at 10kA/20kA
Switching Impulse Residual Voltage	Specified per model
Pressure Relief Class	Available (for heavy-duty models)
Pollution Level / Creepage Distance	Designed for specific pollution severity (e.g., IV)

Benefits for Your Operations:

Enhanced System Reliability: Protects transformers, switchgear, and other expensive equipment from damaging overvoltages, reducing unplanned outages and maintenance costs.
Reduced Maintenance Burden: The polymer housing is resistant to cracking and tracking, and its hydrophobic surface sheds water and contaminants, leading to lower cleaning and inspection requirements.
Improved Safety: The pressure relief design enhances safety for personnel and adjacent equipment. The lightweight nature also reduces installation risks.
Cost-Effective Solution: Offers a favorable balance of initial investment, long service life, and minimal maintenance, providing a strong return on investment over its lifespan.
Wide Application Range: Suitable for protecting substations, overhead transmission lines, cable terminations, and industrial power intakes.

Frequently Asked Questions (FAQ):

Q: What is the primary advantage of a polymer housing over a porcelain one?
A: Polymer housings offer superior pollution performance due to hydrophobic surfaces, are much lighter (easier to install), and are highly resistant to mechanical damage from impact or thermal shock, reducing breakage risks.
Q: For which specific applications is this "Heavy Duty" arrester recommended?
A: It is ideally suited for critical points in the network requiring high energy handling, such as substation entrances, transformer protection, and on important transmission lines where reliability is paramount.
Q: How do I select the correct nominal discharge current (10kA vs 20kA)?
A: Selection depends on the lightning activity level (isokeraunic level) and the importance of the protected equipment. 20kA arresters are typically used in areas with high lightning incidence or for protecting very critical assets. We can advise based on your location and system details.
Q: Does the arrester require regular maintenance or testing?
A: Polymer-housed arresters are generally maintenance-free. However, periodic visual inspections are recommended to check for physical damage or excessive contamination. Leakage current monitoring devices can be used for online condition assessment.
Q: What mounting options are available?
A: Standard models are designed for vertical mounting. However, specific designs for horizontal mounting or with special brackets are available upon request to suit your structural requirements.
Q: Are these arresters suitable for both indoor and outdoor use?
A: Yes, the polymer housing is designed for full outdoor service under various weather conditions. For indoor use, they provide equally effective protection, often in a more compact form factor.
Q: Can you provide custom electrical characteristics or mechanical dimensions?
A: Yes, as a manufacturer, we have the capability to discuss modifications to standard specifications, such as specific residual voltage levels or creepage distances, based on your project's detailed requirements.
Q: What is the typical lead time for an order?
A: Lead times vary based on order quantity and specification. For standard models, we often maintain stock or can produce with relatively short lead times. We provide clear timelines upon receipt of your inquiry.
