Yh5wx-100/260E Polymer Suspended Line Arrester

In modern power transmission and distribution systems, lightning overvoltages are a primary cause of line tripping and equipment damage. Especially in areas with frequent lightning activity or severe pollution, efficient and reliable overvoltage protection is crucial. Weisho Electric, with its 12 years of deep expertise in high-voltage switchgear and overvoltage protection, proudly introduces the Yh5wx-100/260E Polymer Suspended Line Arrester. This innovative product is specifically designed for 35kV and below overhead transmission lines, providing comprehensive lightning and switching overvoltage protection for your power grid with its outstanding energy absorption capability, superior anti-pollution flashover performance, and stable long-term operational reliability.

The "100/260E" in the Yh5wx-100/260E model signifies the arrester's powerful protective capabilities: 100kA represents its ability to withstand a 2ms square wave high-current impulse, demonstrating excellent energy absorption; while 260E refers to its rated voltage level on the high-voltage side. As a polymer arrester, it effectively avoids the drawbacks of traditional porcelain arresters, such as susceptibility to explosion, heavy weight, and difficult maintenance. This makes it an ideal choice for line protection in power systems, especially in unmanned areas. Choosing Weisho Electric's Yh5wx-100/260E means opting for a safer, more reliable, and smarter line protection solution, significantly enhancing power supply continuity and reliability.

Core Advantages & Features: Innovative Technology, Worry-Free Protection

Weisho Electric's Yh5wx-100/260E Polymer Suspended Line Arrester, combining cutting-edge technology and rigorous craftsmanship, offers you the following core advantages:

• 1. Exceptional Energy Absorption & Limiting Capability (100kA High-Current Withstand):

• Technical Detail: Internally utilizes high-performance Metal Oxide Varistor (MOV) blocks, treated with a special formulation and precision sintering process, possessing non-linear V-A characteristics. The Yh5wx-100/260E model boasts a 100kA 2ms square wave high-current withstand capability, far exceeding industry standards, ensuring extremely low residual voltage even when absorbing high-energy lightning impulses, effectively limiting overvoltage.

• Key Benefit: In the event of severe lightning strikes, it can quickly conduct and absorb massive lightning energy while limiting overvoltage on the line to a safe level, significantly reducing lightning-induced tripping and damage risks to equipment such as line insulators, transformers, and circuit breakers, ensuring stable and safe grid operation.

• 2. Superior Anti-Pollution Flashover & Weather Resistance:

• Technical Detail: Features a high-quality silicone rubber composite housing, a material with excellent hydrophobicity, aging resistance, UV resistance, and electrical erosion resistance. The shed structure is optimized to increase creepage distance, effectively preventing pollution accumulation that leads to flashover.

• Key Benefit: Even in harsh environments with heavy pollution, salt spray, humidity, or strong UV radiation, the arrester maintains long-term reliable insulation performance, preventing pollution flashover trips. This is particularly suitable for highly polluted industrial areas, coastal regions, and sandy environments.

• 3. Safe Explosion-Proof Design, Ensuring Personal and Equipment Safety:

• Technical Detail: Employs multiple sealing structures and a special internal pressure release device, ensuring that the arrester can safely vent pressure in the event of extreme overload or internal faults, preventing block explosion and debris scattering. The product strictly adheres to explosion-proof standards.

• Key Benefit: Significantly enhances the operational safety of the equipment itself and the safety of surrounding personnel and equipment, minimizing the occurrence of secondary accidents and complying with stringent electrical safety regulations.

• 4. Lightweight & High Strength, Convenient for Installation and Maintenance:

• Technical Detail: Polymer materials replace traditional porcelain, greatly reducing the arrester's weight, while offering excellent bending strength and seismic performance. The suspended design allows for installation without additional support, directly connected in series on transmission lines or pole cross-arms.

• Key Benefit: Dramatically lowers transportation, installation difficulty, and costs, reduces construction periods and maintenance workload, and simultaneously enhances the line's resistance to damage from natural disasters such as earthquakes.

• 5. Long-Term Operational Reliability & Maintenance-Free Characteristics:

• Advantage: Internal components are well-sealed to prevent moisture ingress. High-quality MOV blocks ensure stable performance with no signs of aging. The polymer housing eliminates the need for regular cleaning and maintenance, significantly reducing operation and maintenance costs.

• Key Benefit: Ensures the arrester's long-term stable operation under severe working conditions, reducing fault rates and downtime, achieving true maintenance-free performance, and providing continuous assurance for grid operation.
