NES-B3 low voltage fully supported Aerial Bundled Conductors

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.
