N-640 Connector (Al / AsXsn)
Universal double-side insulation piercing connector, designed for making safe branch connections from insulated Al main lines with a wide range of cross-sections.
- Main Line (insulated): 6 - 150 mm²
- Branch: 1.5 - 35 mm²
- Shear Torque: 14 Nm
- Compatibility: Al and Cu
Key Advantages of the N-640 Connector
Double-Side Piercing
The connector pierces the insulation on both the main and branch conductors, eliminating the need for insulation stripping and reducing installation time.
Full Safety
The zero-potential bolt enables safe Live Working (Live Line Working - LLW). Connection tightness is guaranteed by a 6 kV voltage test underwater.
14 Nm Shear Head
The use of a shear bolt (size 13 wrench) ensures that optimal electrical contact is obtained without using a torque wrench.

Application and Design
Operational Characteristics:
- UV Resistance: Made of durable materials resistant to atmospheric aging.
- Insulating Cap: Integrated protection for the end of the branch conductor.
- Easy Disassembly: Can be removed using an open-ended wrench.
- Versatility: A single solution for a wide range of cross-sections.
Installation Instructions
- Insert the branch conductor into the hole equipped with the sealing cap.
- Place the connector onto the insulated conductor of the main line.
- Tighten the bolt until the upper part of the head shears off (shear head).
- The connector does not require stripping the insulation from either of the conductors.
The N-640 connector is a proven product by NILED, guaranteeing connection durability under the most demanding weather conditions.
