Product Introduction

High Tension Towers are steel structure towers used to support high-voltage/ultra-high-voltage transmission lines and are applied in power grid and new energy transmission projects.

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.

Core Advantages

High-strength steel: Uses Q235B/Q355B/Q420B steel, with strength matched to voltage ratings. Strong wind and icing resistance reduces the risk of tower collapse.

High-precision joints: Hole spacing deviation ≤ ±1.5mm, ensuring tight component fit, reducing loosening and stress concentration, and extending service life.

High-strength bolts: M16/M20/M24 connections, 8.8 grade high-strength bolts (ultra-high voltage), conforming to GB 50233.
