Insulator Pole Top Pin

Pin for pole top mounting of insulators. The construction is pressed steel and insulator thread cast lead.

Galvanized steel per ASTM A-153

Description

The pole top pin slotted channel sections are mounted against the pole by 5/8-inch bolts. The design of the pole top pin is to allow easy removal for replacement of insulator units or fittings without the necessity to remove the insulator strings from the cross arms. Taporellinefitting pole top pin has the length of 18’’ and 20’’, with 1’’or 1-3/8’’ lead thread. The straight base design has two mounting holes on the base.

The pole top pin is made from hot new rolled steel. The steel will heat to red and punched to the designed shape. The finish of the pole top pin is hot dip galvanized which is reasonably smooth and free of burrs or other sharp projections.

Application:  

Pole top pin is used along with pin insulators mainly on power transmission lines, 11kv/33kv distribution lines, and overhead power lines.

Features:

1) All pole top pins have ANSI standard cast lead threads.

2) The flat side of the flanged channel section is for mounting against the pole with a 5/8 inch bolt.

3)  Eliminate worker handling and environmental disposal concerns associated with lead threads.
