Widely applied for outgoing transmission lines of medium-scale photovoltaic power stations and wind farms, connecting renewable power generation bases to regional central distribution substations.

Coastal, High-Wind & Severe Corrosion Environments

The hot-dip galvanised surface treatment delivers outstanding rust and salt-fog resistance, ensuring stable long-term operation in coastal salt spray areas, high-humidity regions and zones with strong persistent winds.

Cross-Infrastructure Supporting Projects

Applicable for power transmission along electrified highways, railway lines, mining areas and remote field engineering facilities. All towers come with official structural test reports, full ISO certification and abundant international project references; customised structural designs are available to match local wind load parameters, soil bearing conditions and regional electrical technical standards.

Core Installation Specifications & Operation Precautions

1. Key Installation Specifications

Foundation Design Requirements
Foundation forms shall be calculated and designed based on local wind load, soil bearing strength and tower height. Two mainstream solutions are cast-in-place concrete embedded foundations and anchor bolt independent foundations. Excavation depth, geometric dimensions and concrete strength grades must strictly follow official engineering drawings. Backfill soil must be layered and compacted evenly to guarantee sufficient anti-overturning stability for the tower.

Verticality & Position Deviation Standards
After tower erection, the vertical deflection of the tower body shall not exceed 3‰ of the total tower height. Horizontal offset at ground level must comply with transmission line route design; all deviations must stay within the tolerance range specified in national and international power transmission standards.

Multi-Section Pipe Connection Rules
For segmented assembled steel pipe towers, flange joint surfaces must be kept clean and flat before connection. All high-strength connecting bolts shall be tightened symmetrically in cross sequence to reach the designated torque value. Complete lock washers must be installed for every bolt to prevent loosening caused by long-term wind vibration.

Mandatory Earthing Standards
Reliable earthing construction is compulsory for all steel pipe transmission towers. The measured earthing resistance value must satisfy local transmission grid safety specifications. Earthing conductors shall be firmly welded or bolt-fixed to the tower base, and anti-corrosion coating treatment must be applied to all connection joints.

Fitting & Hardware Assembly Criteria
Cross arms, suspension insulators, cable clamps and all auxiliary hardware shall be mounted following the design orientation. Pre-set mounting holes on the tower body cannot be arbitrarily re-drilled or modified without manufacturer approval. The tightening torque of all hardware fasteners must align with the official manufacturer technical manual.

2. Precautions for Transportation & Storage

1.Protect the hot-dip galvanised anti-corrosion layer of the tower pipe body from scratches, collision impact and friction abrasion. Any coating damage discovered shall be repaired immediately with matching anti-rust coating materials.
2.Place soft buffer padding under tower pipes during stacking and transit to avoid local indentation or bending deformation. Do not stack heavy cargo directly on the tower pipe surface.
3.Store finished towers on flat, well-drained ground. Separate stacked layers with wooden support blocks to avoid moisture retention and surface galvanised layer corrosion.

3. On-Site Installation Safety Precautions

1.Only use the designated hoisting binding positions marked on the tower body. Improper lifting binding points will cause permanent bending deformation of the steel pipe tower.
2.Do not drill new holes or cut the tower pipe body without formal technical approval from the manufacturer, as this will weaken the overall structural bearing strength.
3.Tighten all flange high-strength bolts symmetrically to the specified torque; conduct a full secondary re-inspection of bolt tightness after installation completion.
4.Strictly control tower vertical deflection within 3‰ of tower height; ensure thorough foundation compaction to eliminate tower tilt and overturn risks.
5.Complete reliable earthing connection construction and test earthing resistance to meet local transmission grid safety standards before power transmission.
6.Halt all erection construction work during thunderstorms, heavy rainfall and strong wind weather to avoid safety accidents.

4. Operation & Daily Maintenance Precautions

1.Do not attach extra hardware, cables or electrical equipment that exceeds the tower’s designed maximum load capacity.
2.Carry out regular periodic inspections to check for bolt loosening, galvanised coating peeling, rust spots and visible tower body deformation.
3.Promptly repair damaged galvanised layers to slow corrosion progression, especially for towers deployed in coastal and high-humidity corrosive regions.
4.Prevent heavy construction machinery from colliding with tower foundations; install obvious warning signs for towers located alongside road traffic routes.
5.Keep complete written records of all inspection results; carry out structural reinforcement treatment immediately once abnormal conditions are detected.

Standard Routine Maintenance Guidelines for Steel Pipe Transmission Tower

1. Visual Overall Inspection (Cycle: Quarterly / Semi-Annually)

● Check the tower pipe body for bending, dents, cracks and abnormal structural deformation.
● Inspect the hot-dip galvanised coating surface: identify peeling, chipping and rust stains, with focus areas on flange joints, welding seams and the tower base section.
● Examine cross arms, insulators, connecting hardware and power cables for damage, aging or positional displacement.
● Confirm no tree branches, foreign debris or piled materials lean against the tower body.

2. Connection Bolt & Fitting Inspection

● Check all flange connecting bolts, fasteners and lock washers for loosening, rust corrosion or missing parts.
● Retighten loose bolts to the required torque standard; replace severely corroded hardware accessories.
● Inspect earthing connection joints to ensure tight contact without oxidation or breakage.

3. Foundation & Surrounding Environment Inspection

● Check tower foundations for settlement, surface cracking, water accumulation or surrounding soil erosion.
● Clear piled soil, weeds and ponding around the tower base to prevent accelerated foundation and pipe corrosion.
● Monitor tower verticality; arrange reinforcement rectification immediately if obvious tilt is found.

4. Annual Earthing Performance Test

● Measure tower earthing resistance once per year to comply with local transmission line safety specifications.
● Repair broken or heavily corroded earthing conductors and rework connection joints if resistance test values exceed standard limits.

Frequently Asked Questions (FAQ) for Steel Pipe Transmission Tower

Q1: What anti-corrosion treatment do you adopt for steel pipe transmission towers?
