110kV - 750kV Transmission Line Tower

Qingdao BEST Steel Structure Co., Ltd. is one of the leading manufacturers and suppliers of 110kv - 750kv transmission line tower in China. With abundant experience, Our factory offer high quality products made in China with competitive price. Welcome to contact us for customized service and OEM service.

110kV-750kV transmission line towers serve as the core supporting equipment in high-voltage and extra-high voltage power transmission projects. They are mainly used to overhead support transmission conductors, lightning shield wires and all kinds of matching power fittings, stably erect high-voltage transmission lines of various circuits, and effectively separate and arrange line layouts. Providing reliable structural support and electrical safety assurance for long-distance, large-capacity and cross-regional power transmission, these towers are widely adopted in main power grid construction, inter-provincial power transportation, urban high-voltage grid expansion and power supporting projects in remote areas. Adaptable to diverse complex terrains and transmission operating conditions, they ensure continuous, safe and stable operation of high-voltage power systems, acting as vital infrastructure to maintain smooth power delivery across the grid and realize long-distance electric energy scheduling and transportation.

Robust Disaster-Resistant Mechanical Structure with Stable Operation: Optimized via refined mechanical simulation, the tower adopts a stable spatial lattice stress system with a well-balanced center of gravity and outstanding anti-overturning and anti-deformation performance. It can withstand extreme weather such as strong winds, heavy snow, ice coating and low temperatures, effectively eliminating safety hazards including tower tilting, deformation and collapse. It ensures uninterrupted stable power supply of high-voltage transmission lines under complex meteorological conditions and suits high-load and high-risk power transmission scenarios.

Compact Footprint & Excellent Engineering Adaptability: Structural optimization reduces the floor area of tower foundations, greatly cutting land occupation and land acquisition costs compared with conventional heavy-duty high-voltage towers. It fits transmission projects in land-scarce areas such as urban districts, farmlands and ecological reserves. Meanwhile, optimized lightweight tower structure facilitates transportation, hoisting and construction, significantly shortening the construction period of high-voltage transmission projects.

Standardized Compliant Production & High Safety Reliability: Manufactured in strict accordance with national and international power engineering standards for high-voltage transmission. Dimensions, mechanical load parameters and electrical parameters of all components are precisely controlled, and spare parts feature strong universality and interchangeability. Every finished tower undergoes multiple quality inspections including load testing, insulation detection and structural flaw detection, delivering consistent and stable products that meet stringent construction and operation requirements of national key high-voltage transmission projects.

Graded Insulation Design Matching Different Voltage Levels: Customized insulation configurations are developed for all voltage grades ranging from 110kV to 750kV. High-strength insulator strings with matched disc quantities are configured for different voltage classes, with precise control over safe electrical clearances between conductors and the ground, conductors and tower bodies, as well as phase-to-phase clearances. It effectively prevents electrical faults like high-voltage flashover, creepage and discharge, fully complying with safety standards for high and extra-high voltage power transmission and guaranteeing stable long-distance power delivery.

Standardized Modular Structure with Superior Versatility: Designed with industry-standard modular splicing, this product covers multiple tower types including tangent towers, tension towers, angle towers and terminal towers, enabling flexible selection and combination based on line routes, spans and terrain conditions. It supports single-circuit, double-circuit and multi-circuit wiring layouts, adapting to diverse complex landforms such as plains, mountains, hills and deserts, and satisfying various engineering applications including trunk power transmission and cross-regional power delivery.

All the production process are carried on by regularly calibrated and well maintained equipment operated by qualified and experienced professionals. The shopfloor logistic is organized by process flow and managed with 5S principle and lean production philosophy with top industrial level process control monitored by fully employed quality control staff. Major processes suitable for automation are all done on automatic machines tools such as CNC punching machine, CNC drilling machine, CNC sub-arc welding machine. Manual welding are all inspected and NDT tested according to industry standard or client's requirements.

We are operating with ISO9001:2015 and GB50661-2011 standards to guarantee work quality process stability and tracability. The company is also certified with ISO45001 and ISO14001 for compliance of safety, health and environment protection.
