LV Double Pull Wire Power Link Line Board is a **high-performance insulated connection device** designed by Handan Jinmai Fastener Manufacturing Co., Ltd. for low-voltage power distribution lines. This product adopts a modular design, integrating wire fixation, insulation isolation and current conduction functions. It is suitable for **power distribution network transformation, communication base stations, outdoor lighting systems** and other scenarios. It can safely connect two parallel wires and maintain stable electrical performance, effectively preventing short circuits, arcs and leakage risks. It is a core component to improve the safety and maintenance efficiency of power lines.
1. Double-tension stable structure
Independent tension adjustment mechanism on both sides ensures that the two wires are evenly stressed, with a tensile strength of ≥10kN, and can resist strong wind vibration.
2. Triple insulation protection
The substrate is made of **glass fiber reinforced polycarbonate**, the slot is embedded with an engineering rubber seal, the surface is covered with an anti-ultraviolet coating, and the insulation resistance is >1000MΩ.
3. All-environment weather-resistant design
Passed salt spray test (500 hours) and high and low temperature cycle (-40℃~+85℃), adapting to harsh environments such as coastal areas, high temperature, and high humidity.
4. Tool-free quick installation
Self-locking wedge-shaped buckle structure, completes wire fixation within 30 seconds, and supports live operation.
5. Intelligent compatibility
Adapts to copper cable/aluminum cable (section 6mm²~35mm²), reserved grounding terminal interface, in line with IEC 61238 standard.
Handan Jinmai adopts a full-process digital quality control system to ensure product consistency:
1. Precision stamping
The high-strength aluminum alloy substrate is integrally formed by the CNC machining center, with a tolerance control of ±0.05mm.
2. Injection molding and coating process
German Bayer flame-retardant engineering plastics (UL94 V-0 grade) are high-pressure injection molded to wrap metal parts to achieve insulation-structure integration.
3. Surface strengthening treatment
The substrate is subjected to triple anti-corrosion treatment of passivation → hot-dip galvanizing (80μm) → epoxy powder spraying.
4. 100% performance test
Each product passes 5kV withstand voltage test, conduction impedance test and mechanical fatigue test.
