As low-voltage (LV) overhead power distribution networks continue to expand worldwide, utilities and electrical contractors require connection solutions that are safe, reliable, fast to install, and capable of operating for decades under harsh environmental conditions. Among the most widely adopted technologies for LV aerial bundled cable (ABC) systems is the Connecteur-CBP/CT70 pour branchement BT, commonly referred to as the CBP/CT70 Low Voltage Insulation Piercing Connector (IPC).
Designed specifically for low-voltage branch connections, the CBP/CT70 connector eliminates the need to strip cable insulation before installation. Instead, specially engineered contact teeth pierce the insulation during tightening, establishing a secure electrical connection while maintaining the integrity of the cable insulation and waterproof sealing. Similar connector families are widely used by European utilities for insulated overhead LV networks and comply with standards such as EN 50483 and NFC 33-020.
The Connecteur-CBP/CT70 is an insulation piercing connector intended for branch connections in low-voltage aerial bundled conductor (ABC) networks.
Instead of removing insulation manually, installers simply position the main conductor and branch conductor inside the connector. As the shear-head bolt is tightened, hardened conductive teeth penetrate both insulation layers and establish a low-resistance electrical connection. Once the required installation torque is reached, the bolt head shears off automatically, ensuring consistent installation quality. This operating principle is common among CBS/CT70-style branch connectors used in LV overhead distribution systems.
Typical applications include:
Traditional cable joining requires a series of cumbersome operations: insulation stripping, grease application, compression sleeve fitting, hydraulic crimping and subsequent insulation re-wrapping.
These steps prolong installation work and leave greater room for installation faults.
Insulation Piercing Connectors (IPCs) combine electrical contact, waterproof sealing, mechanical retention, torque control and corrosion resistance into one compact component.
Eliminating complicated multi-step assembly, IPCs have gained growing popularity among power utilities across Europe, Asia, Africa and Latin America for overhead distribution line applications.
A premium-quality connector generally consists of:
1). UV Resistant Polymer Body
The housing protects the connector from:
2). Aluminum or Tinned Copper Contact Plates
High-conductivity contact blades ensure:
3). Shear Head Bolt
The calibrated bolt guarantees:
4). Waterproof Elastomer Seals
These seals prevent:
5. Corrosion Resistant Hardware
Typically manufactured using:
The CBP/CT70 insulation piercing connector (IPC) has earned a strong reputation in the low-voltage (LV) electrical distribution industry thanks to its reliable performance, quick installation, and long service life. It is widely used for service connections in Aerial Bundled Cable (ABC) systems, allowing utilities and electrical contractors to create secure branch connections without removing cable insulation.
However, the global market offers numerous alternatives to the CBP/CT70 connector. Various manufacturers produce similar connection solutions designed to meet the requirements of low-voltage distribution systems, utility service drops, public lighting networks, and rural electrification projects. While these products share the same fundamental operating principle, they can differ significantly in design, conductor range, material quality, installation torque, environmental resistance, and compliance with international standards.
For distributors, utility companies, EPC contractors, and procurement managers, understanding the available alternatives is essential for selecting the most suitable connector for each application.
