UJ-1880 is a U-shaped screw used for power system, which belongs to a kind of connecting fittings, mainly used for hanging and fixing wires, insulators and other equipment

definition

UJ-1880 is a kind of connecting fittings in power fittings, mainly used for hanging and fixing wires, insulators and other equipment. It is fixed with the pole and tower crossarm by bolt connection, so that the crossarm structure is simplified

material

The material of UJ-1880 is usually Q235 steel or 316 stainless steel, and the surface treatment is mostly hot-dip galvanized to improve its corrosion resistance.

effect

UJ-1880 is mainly used to connect and fix wires, insulators and other equipment in the power system to ensure the stable operation of power lines. Specific roles include:

Suspension of suspended insulator strings

Fixing of the overhang combination of lightning arrester

First piece of pole and tower crossarm connection

Usage

The UJ-1880 is fixed to the pole and tower crossarm by bolted connection, which simplifies the crossarm structure. It is usually used in linear pole tower suspension suspension insulator string, lightning rod suspension combination and other scenes
