JUNW JJC Series Insulation Piercing Connector

JUNW JJC Series Insulation Piercing Connectors (IPCs)
1.Core Product Advantages & Overall Features
JUNW JJC Series Insulation Piercing Connectors are high-performance low-voltage distribution connection components, designed for no-stripping, live-line, tool-efficient installation for overhead and underground power cables. Key competitive advantages:
•Innovative Piercing Technology: Specialized piercing blades penetrate cable insulation without damaging conductors, supporting 1.5–240mm² copper/aluminum (Cu/Al) cables and same/different diameter wire tapping, eliminating the need for extra terminal blocks or junction boxes.
•Reliable & Durable Performance: Torque-controlled nuts ensure consistent, secure piercing pressure; a self-sealing structure delivers waterproof, dustproof, anti-corrosion, UV-resistant performance, with 6kV insulation strength, 15kA impulse current capacity, and compliance with GB2314-1997 standards, backed by a 30-year proven service life.
•Cost & Space Efficiency: Reduces installation space, eliminates cable return lines and terminal boxes, cutting construction and material costs, making it ideal for smart grid upgrades, building distribution, and renewable energy projects.
•Safety & Stability: Excellent mechanical strength, low temperature rise, and stable heat cycle performance ensure long-term reliability in harsh outdoor environments.
