Insulation Piercing Connectors

Insulation Piercing Connectors for Low-Voltage Overhead Lines

With Avantar's insulation piercing connectors (IPCs), workers can connect to insulated wires above them without having to take off the jacket. Piercing teeth made of aluminium or copper cut through the insulation to make a stable metal-to-metal contact. This happens all at once when the bolt is tightened. A torque-controlled shear-head bolt breaks off automatically at the right torque, so you don't have to guess when to install it. The UV-resistant and IP54-sealed polymer housing can be used outside all the time. It can handle up to 1 kV and meets the requirements of IEC 61238 and NFC 33-020.

Key Features

There is no need for insulation stripping. The piercing teeth go through the cable jacket and make an electrical connection all at once. This speeds up the installation process and eliminates the chance of damaging the conductor strands.

The torque-controlled shear-head bolt cuts at the right torque every time. This keeps the link safe from both too little and too much torque without the need for a separate torque wrench.

It is possible to put over a live line. Overhead lines that are already live can be used to connect branches. This cuts down on the expected downtime for distribution upgrades or service-drop work.

The UV-resistant and IP54-sealed polymer housing protects against moisture, dust, and damage from the sun for a long time in outdoor and underground junction applications.

Typical Applications

The products are commonly specified for:

• Low-voltage overhead distribution networks
• Street-lighting branch taps
• Service drop connections from the main line to premises
• Renewable energy grid-connection points
• Outdoor and underground secondary distribution junction boxes

Technical Specifications

Custom Design Options

Standard catalog models cover the most common conductor cross-section combinations. For projects that use non-standard cable sizes or require specific contact-tooth materials, Avantar supports OEM and ODM development based on customer drawings and technical specifications.

Configurable parameters include main and branch conductor range, aluminum or copper piercing teeth matched to your local cable material, and housing color or labeling for project identification. Sample evaluation against your actual cable type and site conditions is available before bulk order placement.

How to Select the Right Model?

Four parameters for Insulation Piercing Connectors need to be confirmed before placing an order:

1. Main conductor cross-section — 16 mm² to 240 mm²
2. Branch conductor cross-section — 6 mm² to 95 mm²
3. Contact-tooth material — aluminum or copper, matched to your cable conductor material
4. Compliance requirement — IEC 61238 / NFC 33-020 and IP54 sealing are standard on all catalog models

Share your cable specifications and installation environment with our team. We will confirm the correct model and provide the corresponding technical datasheet.

Packaging and Logistics

Each connector is packed in moisture-proof plastic bags and placed in standard export cartons to protect against dust and moisture during transit.

Full export documentation is provided with every shipment, including a certificate of origin and CE and RoHS test reports for customs clearance and tender submission. Quotations are available under EXW, FOB, and other standard trade terms. Sea freight, air freight, and express courier options are supported from our Guangdong facility, near the ports of Shenzhen and Guangzhou.

FAQ

Q: Are these connectors safe to use on live, energised lines?

A: Yes. Live-line installation is possible with these items. Overhead wires that are already live can be used to connect branch lines, which cuts down on the need for planned outages during network upgrades or new service connections.

Q: Does Avantar make things or do they just sell them?

A: Avantar is a direct manufacturer with its headquarters in Guangdong, China. Sourcing directly speeds up technical consultations and gets rid of the middlemen who add costs to buying things like utilities, streetlights, and renewable energy.

Q: What kinds of paperwork are there for clearing customs and submitting bids?

A: Every sale comes with paperwork for CE, RoHS, and UL 486A/B. In the standard export package, there is a certificate of origin and test reports. For special tender needs, please contact our team with the documentation checklist, and we'll let you know if the documents are available.

Q: How can I be sure of the quality of a product before I place a large order?

A: You can get a sample to look over before you place a bulk order. Before confirming the production order, you can compare the sample to your real cable type and the conditions of the environment. You can also look over the dimension and torque performance records.

Q: What is the minimum order quantity (MOQ) and lead time for regular catalogue items?

A: No, the standard MOQ for each model is 1,000 pieces. It takes 5–10 working days for standard catalogue items to get to you after you confirm your order. Send us the details of the cable you need, and we'll give you a model suggestion and a written quote.
