Thermal Explosive Disconnector (TLB): Provides safe disconnection of faulty arresters by detecting excessive current and ensuring rapid separation.
Lightning Arrester Counter / Online Monitor: Records the operating condition of arresters, enabling accurate monitoring and maintenance. Available in outdoor dial-type and cabinet-mounted versions.
Surge Arresters (HY5WZ / HY5W / HY5WS series): Designed for different system voltage levels (3kV~220kV), these arresters offer strong overvoltage protection, low leakage current, and high energy absorption capacity.
Power substations (35kV and above)
Transmission and distribution networks
Industrial electrical systems
Transformer and capacitor bank protection
Railways, petrochemical plants, and other critical infrastructure
Fast action with multiple operating times depending on current levels
Ensures safe separation of faulty arresters
Compact, reliable, and maintenance-free
Records the number of operations of arresters
Optional current monitoring function for enhanced protection
Available in different types: outdoor dial, cabinet split type, simple counter, and advanced current-monitoring models
Wide system voltage range (3~220kV)
High discharge capacity (up to 40kA impulse current)
Excellent leakage current control (≤50μA)

Q1: What is the purpose of a thermal explosive disconnector (TLB)?
A1: It disconnects a faulty arrester from the system safely when overcurrent occurs, preventing damage and accidents.
Q2: How does the lightning arrester counter help?
A2: It records the number of operations of the arrester and monitors leakage current (in advanced models), making maintenance more efficient.
Q3: What voltage range do these surge arresters cover?
A3: Our surge arresters are suitable for 3kV to 220kV systems, covering both substations and distribution networks.
Q4: Are the products compliant with international standards?
A4: Yes, they are designed and manufactured according to IEC and GB standards.
Q5: Can I request customized specifications?
A5: Yes, we can provide tailored solutions based on customer requirements.
