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: Good mechanical strength, low temperature rise, and stable heat cycle performance ensure long-term reliability in harsh outdoor environments.
2.Model-Specific Differentiation
•JJC-1: Compact entry-level model, 1.5–35mm² main line / 1.5–10mm² branch line, 41A rated current, 10g weight, 1 bolt, tailored for small-load residential tapping.
•JJC-2: Medium main line model, 16–95mm² main line / 1.5–10mm² branch line, 55A rated current, 55g weight, 1 bolt, suited for small commercial distribution tapping.
•JJC-3: Medium-power model, 16–95mm² main line / 4–35(50)mm² branch line, 157A rated current, 160g weight, 1 bolt, ideal for industrial and commercial medium-power tapping.
•JJC-4: Large main line compatible model, 50–150mm² main line / 6–35(50)mm² branch line, 157A rated current, 162g weight, 1 bolt, for high-power main line tapping in distribution networks.
•JJC-5: Equal-section tapping model, 25–95mm² / 16–120mm² main/branch line, 157A/214A rated current, 198g weight, 1 bolt, for same-section cable branching in distribution systems.
•JJC-6: High-current equal-section model, 50–150mm² main/branch line, 316A rated current, 280g weight, 1 bolt, built for heavy-load industrial and high-power distribution tapping.
•JJC-7: Dual-spec large main line model, two variants: 120–240mm² main / 25–120mm² branch (276A) and 150–240mm² main / 10–25mm² branch (102A), 360/336g weight, 1 bolt, for utility grid flexible tapping.
