Product Description
As overhead distribution networks expand, line crews often need a connector that can tap an insulated conductor without stripping the jacket. The Smico TTD151F insulation piercing connector (IPC) addresses that field condition. Its teeth are offered in copper or aluminium to match the conductor material, the body is PA66 fiberglass for fire resistance and mechanical rigidity, and the M8 bolt is rated at 13 Nm torque. A zinc alloy shear head provides a repeatable tightening indication on the pole or in the bucket.

Installation & Operation Notes
Field installation centers on the M8 bolt and 13 Nm torque value. The zinc alloy shear head is designed to separate when the rated torque is reached, removing the need for a torque wrench on every connection — crews tighten until the head shears, then visually confirm the break. Teeth material (copper or aluminium) should be selected according to the line conductor; the body is black PA66 fiberglass, suitable for exposed overhead environments. Units are packed in export cartons for distribution. Confirm conductor range and insulation diameter with the supplier before ordering for a specific circuit.
Applications
Listed usage covers substation fittings, line fittings, and insulation piercing connectors. The TTD151F fits electric power fitting applications where an insulated conductor must be tapped without cutting or stripping, such as overhead service drops, street lighting taps, and secondary distribution connections. Because the connector is fireproof and rated for line use, procurement teams typically request it for outdoor overhead networks where joint reliability and minimal inventory complexity matter.
