The power angle iron crossarm is an important component used to support conductors, lightning arresters and fixed insulators in power lines. Its specifications and sizes need to be determined according to the voltage level, line type and installation requirements.
Product Detail
The following is a detailed introduction to its common specifications and sizes:
Common specifications
1. High-voltage lines (10kV and above)
Standard angle steel model: Hot-dip galvanized angle steel is usually used. Common specifications include:
∠63×6 (side length 63mm, thickness 6mm), suitable for straight poles, jumper crossarms, etc., the length is generally 1500mm, 1700mm, 2000mm, 2100mm, etc.
∠75×8 (side length 75mm, thickness 8mm), used for double-pole low-voltage crossarms or long-span lines, the length is mostly 1500mm, 1800mm, 3400mm.
∠80×8** (side length 80mm, thickness 8mm), suitable for large span or high load lines, such as 5100mm, 6500mm and other long crossarms.
2. Low voltage lines (such as 380V/220V)
Low voltage crossarm: Common specifications are ∠60×6 (side length 60mm, thickness 6mm), and the length is generally 1500mm.
3. Special purpose crossarms**
Jumper crossarm: ∠63×6×2100mm.
Four-wire crossarm: ∠63×6×1800mm.
Drop-out fuse crossarm: ∠63×6×2300mm.
The length of high voltage crossarm is generally 1700mm (standard straight pole), and low voltage is 1500mm; special scenes such as corner poles or tension poles need to be lengthened.
Materials and Processes
-Material: Mostly hot-dip galvanized angle steel, which is highly corrosion-resistant and suitable for outdoor environments.
-Method of representation: Specifications are usually marked as "∠ side length × thickness × length", for example ∠63 × 6 × 2000mm.
Differences in regions and standards
The power supply standards in different regions may affect the selection of crossarm size. There are differences in different regions, and it is necessary to select according to the geographical conditions and environment of the construction site.
There are holes of different sizes on the crossarm. The size of the hole is determined by the element that passes through it.
This set of pole hardware accessories has different sizes or specifications. The size is measured in top surface, length and side depth. When purchasing a power crossarm, you should specify the size that suits you.
