Introduction

High Tension Wire Tower supports high-voltage transmission lines from 110kV to 1000kV. It is used in power transmission networks, especially in areas with long spans, high winds, or heavy ice loads.

Parameter

Parameter Category	Key Indicators	Remark
Material	Q235B (standard), Q355B (medium-high pressure), Q420B (extra-high pressure)	High-strength steel is used in areas subjected to heavy loads.
Angle steel specifications	Double-leg/Single-leg angles: L50×5 to L200×20; Large sizes: L200×20 to L400×30	Selected based on load capacity, ultra-high voltage lines often use double conductors.
Connection method	Bolted connections are primarily used, with M16/M20/M24 bolts; 8.8 grade high-strength bolts (for extra-high voltage applications).	Torque shall be in accordance with GB 50233-2014.
Node requirements	Bolt hole spacing deviation ≤ ±1.5mm; contact surfaces fit well with no noticeable gaps.
