As low-voltage (LV) power distribution networks continue to expand worldwide, utilities and electrical contractors require reliable, safe, and cost-effective connection solutions. Among the most widely used accessories in overhead insulated cable systems is the Double Bolt Insulation Piercing Connector (IPC).

What Is a Double Bolt Insulation Piercing Connector?

A double bolt insulation piercing connector is a mechanical electrical connector used to create branch or service connections on insulated conductors without removing the cable insulation.


The connector consists of:

  • High-strength engineering polymer housing
  • Corrosion-resistant aluminum alloy contact plates
  • Insulated shear-head bolts
  • Waterproof sealing components

During installation, the bolts are tightened until the contact teeth pierce the conductor insulation and establish a secure electrical connection.

ZOP-257 is outstanding among double bolt insulation piercing connectors available on the market today.The ZOP-257 Insulation Piercing Connector is designed to establish electrical connections without stripping the insulation of conductors. It is widely used in low-voltage aerial bundled cable (ABC) systems for branch connections, service lines, and street lighting networks.
