Product Description

NES-B3 low voltage fully supported Aerial Bundled Conductors

Material：Mild steel ,nylon plus fiber glass

Product property：It is used to terminate 4-core of aerial bundle conductor .Its function is fixing and tightening the insulation conductor .

The arms are made of hot-dip galvanised steel. A bolt enables the clamp to be easily dismantled manually and an- chored on a bracket fixed to a pole or façade.

- The cleats are made of UV resistant, glass fibre reinforced synthetic material.

- The conductors are attached using a combination of bolts and cleats. Two 17mm shear head nuts are used to control

the tightening torque.

- Each conductor runs through a separate channel. The conductors are anchored by distributing the loads, protecting

the insulation.

- A large opening facilitates the passage of the conductors between the clamp arms.

- The mechanical resistance is 3300daN for the NES-B2, and is greater than 5000daN for the NES-B3.

This clamp meets the criteria of the DIN VDE 0211 standard.

Implementation

- Unscrew the nuts.

- Open the A.B.C and insert each conductor into one of the channels.

- Screw the nuts alternately using a 17mm spanner until the shear head breaks. The 21mm head is only provided for

possible dismantling.

- Anchor the clamp on a hook.

- Additional tightening is achieved automatically by the cleats.
