The NIU Electric 2D55-P00147P1 Overhead Line Fitting Connector is a high-performance component within the 2D55 Overhead Fittings series, created to ensure safe, efficient, and long-lasting electrical connectivity for modern power distribution networks.
Built from corrosion-resistant aluminium alloy with precision-machined surfaces, the connector combines light weight with high mechanical strength. It maintains firm contact under tension, vibration, and temperature fluctuations, guaranteeing reliable conductivity and minimal maintenance throughout its service life.
The design delivers low contact resistance, stable current flow, and strong tensile capability. A secure clamping mechanism and anti-slip grooves prevent conductor loosening, while the simplified tightening process allows quick, safe field installation for overhead systems.
Fully compatible with other 2D55 Overhead Fittings — such as suspension and tension clamps — the 2D55-P00147P1 serves utility grids, industrial overhead lines, and renewable energy arrays. It enhances operational efficiency and ensures long-term reliability in demanding outdoor environments.
Application:
1. The 2D55 insulation piercing connectors are applicable for all types of LV-ABC.
2. Had passed 6KV test under water for 1 Min.
Feature:
1. Simple installation, small contact resistance and low temperaturerise of the clamp. The body materials are UV-resistant.
2. Its self-seam frame is wet proof, water proof, and anti-corrosive,which can prolong the using life of insulated lead and connector.
3. Standard: EN 50483-4, NFC 33-020, NFC 33-004
