Insulation Piercing Connector (TTD) Introduction

Engineered for reliable branch connections, insulation piercing wire connectors are primarily specified for main and tap line configurations using insulated copper or aluminum conductors. Manufactured with a high-strength, climatic and mechanically resistant insulating body, these connectors feature a plurality of prongs with forward-tapering top edges on the wire barrel-incorporating corrosion-resistant tight bolts, torque shear nuts, and a slide-assisted lower/upper tool mechanism to ensure precise contact-to-housing assembly and optimal electrical termination.

This product is highly suitable for watertight overhead and tap distribution applications requiring stable contact pressure and fast, simple installation. Where demanding environmental protection and dependable dielectric strength are required, its sealed structure withstands 6kV flashover in water-pairing a stable piercing mechanism with a versatile, optional waterproof soft cap that can be separated on either the left or right side to prevent moisture ingress without requiring complex site procedures.

■Universal compatibility for insulated copper or aluminum conductors across main and tap line connections

■High-strength, climate and mechanically resistant insulating body integrated with forward-tapering piercing prongs

■Corrosion-treated tight bolts equipped with shear torque nuts for safe, simple, and rapid tool installation

■Watertight sealed construction withstanding 6kV flashover in water with a flexible, detachable tap cap

Characteristics

Featuring a high-strength, climatic and mechanically resistant insulating housing, these TTD insulation piercing connectors boast a specialized branch termination design, where forward-tapering prongs on the wire barrel and slide-assisted tool assembly are engineered to establish optimal electrical connection across insulated copper or aluminum conductors. Constructed for watertight overhead and tap distribution securing, the connectors incorporate corrosion-treated tight bolts and torque-shear nuts-ensuring precise physical fit and adaptable piercing contact without stripping cable insulation.

This product is highly suitable for tap line connection applications requiring reliable dielectric strength and fast, simple installation procedures. Where demanding environmental conditions and watertight connection integrity are required, its fully sealed manufacturing provides a far more efficient solution than standard jointing methods-withstanding 6kV flashover in water and integrating an optional, side-separable waterproof soft cap to ensure long-term moisture protection without requiring post-site modifications.
