Installation Method And Effect Of Galvanized Cross Arm For Household Use

The poles use double cross arms at the beginning and end, corners, and crossing rivers, roads, and railways, and the rest generally use single cross arms.

Two-point buried type: the angle iron is U-shaped, and both ends are buried in the wall and fixed with concrete or mortar.

One-point buried type: drill a hole in the wall, bury one end of the angle iron in the wall, and fix it with concrete or mortar. Bolt fixed type: directly fix with expansion bolts, generally the cross arm entering the house is T-shaped or triangular. The single cross arm of the pole should be installed on the power receiving side. When a single cross arm is used for a 90° corner pole and a terminal pole, it should be installed on the wire pulling side; a single cross arm should be used for a corner pole below 15°; a double cross arm should be used for a corner pole from 15° to 45°; a cross cross arm should be used for a corner pole above 45°.

According to the economic utilization of Pole mounted fuse switch, the layout method can be divided into three types: layout with waste, layout with less waste and layout without waste. According to the layout form of the parts on the material, the layout can be straight, oblique, opposite, mixed, multiple, etc. Because the parts involved are rectangular parts and the four holes have position tolerance requirements, the straight layout method with waste is adopted.
