YH5WX-51/134E 35KV Suspended Gapless Line Lightning Arrester

Product Information

Product Overview: The YH5WX-51/134E series lightning arrester uses advanced zinc oxide varistor technology and a polymer housing. It is specifically designed to protect transmission lines and power distribution systems from lightning overvoltages and switching overvoltages.
[Key Advantages]

Superior Protection: Its non-linear current-voltage characteristic effectively limits lightning impulse waves to prevent damage to equipment.
Polymer Housing: The housing offers excellent anti-pollution, explosion-proof, and moisture-proof properties. Its lightweight nature simplifies installation procedures.
Maintenance-Free Design: As a gapless lightning arrester, it requires no routine maintenance, ensuring long-term reliable operation.
Wide Applicability: Suitable for AC power systems from 10kV to 220kV, it can be installed on transmission line suspension or pole structures.

YH5WX-51/134E 35KV Suspended Gapless Line Lightning Arrester

Technical & Professional Details

[Structure and Operating Principles]

The YH5WX-51/134E arrester consists of core zinc oxide (ZnO) resistor blocks and a silicone polymer housing. Under normal operating voltage, the resistor blocks are highly resistive, conducting minimal current. When subjected to lightning overvoltage, the resistance rapidly drops, diverting the overvoltage energy to the ground, thereby effectively protecting transformers and switchgear. The polymer housing provides superior insulation and sealing.

[Frequently Asked Questions (FAQ)]

Q: How do I choose the right arrester model?
A: You should select a model based on factors like your system's rated voltage, insulation level, geographical environment, and lightning density. If you are unsure, please contact our experts for a tailored arrester selection plan.
Q: Does this arrester require maintenance?
A: Our gapless arresters are designed to be maintenance-free, eliminating the need for routine inspections or tests and significantly reducing operation and maintenance costs.
Q: What is the difference between a gapless and a gapped arrester?
A: A gapless arrester, without series gaps, can provide continuous and effective protection with a faster response time. Gapped arresters require a higher voltage to discharge and have a slight delay in response.
