Pole Mounting Method For Vertical Fuse Disconnect Switches

The pole-mounted frame allows the vertical fuse switch disconnector to be directly fixed to the distribution pole or supporting crossarm. First, select a mounting bracket that matches the pole or crossarm and securely fix the bracket to the pole or crossarm structure, ensuring the switch base aligns with the bracket's mounting holes. This method typically does not require drilling holes in the pole.

After installation, hang the disconnect switch body into the bracket and secure it with bolts, washers, and locking devices. Verify the grounding connection points to ensure the entire device is stable and reliable. Keep moving parts vertical or slightly tilted vertical to facilitate subsequent operation using the operating lever.

Next, connect the incoming and outgoing terminals. If using aluminum wire, clean the wire ends and apply an anti-oxidant before tightening. After connecting the wires, ensure a tight connection and neat arrangement to facilitate stable current conduction and avoid affecting the contact between the fuse and contacts.

Finally, complete the closing and opening operations from the ground using the insulated operating lever. The contact positions of the moving and stationary contacts should meet design requirements to ensure smooth operation and reliable contact. This pole-mounted installation method makes the nhrt40 vertical fuse switch disconnector suitable for outdoor power distribution systems. Its overall structure is compact and easy to install, making it suitable for overhead or pole-mounted wiring scenarios.
