Power Transmission Steel Towers are used for electrical transmission and distribution. It is set up outdoor, including many types for 110-500 KV electricity transmission lines.
OMSE project team can carry out all kinds of energy transmission line tower design and, if requested, type tests of these structures are made at international and accredited stations. Besides, static controls of designs from customers and end-users, manufacturing drawings and manufacturing cards can be prepared by the OMSE project team.
All the products that have not been manufactured before, prototype installation and then prototype controls are carried out by OMSE quality teams. After all the details have been examined If it is required, revisions are made, and serial manufacturing phase is initiated. If requested, our customers and end-user management authorities can participate in prototype inspections.
1-Lattice Towers
Lattice towers are the most common type of transmission towers, consisting of steel frames that form a triangular or square shape. They are strong, flexible, and easy to assemble and transport. Lattice towers can support multiple circuits and span long distances, making them suitable for most terrains and weather conditions. However, they also have some drawbacks, such as high maintenance costs, visual impact, and susceptibility to corrosion and bird collisions.
2-Tubular Towers
Tubular towers are made of hollow steel tubes that are welded or bolted together. They are more compact, aesthetic, and resistant to corrosion than lattice towers, but they are also more expensive, heavier, and harder to transport and install. Tubular towers can support single or double circuits and are often used in urban areas, where space is limited and visual appeal is important. They can also be designed to have different shapes, such as monopoles, H-frames, or delta configurations.
The towers are formulated to house a variety of accessories which include platforms, ladder ear, step bolts, safety cage and so on. Our latticed tower can be used in these fields such as electric power transmission line tower, telecommunication tower, broadcasting tower, watching tower, microwave tower, mapping tower, communication tower, crossing-river tower and other applications.

110kV Class Power Transformers
General
The110kV class low loss transformers are developed by Huapengour workshop through years of service experience and careful analysis of the advantages and disadvantages of the transformers of different manufacturers, both domestic and abroad, and are featured by low loss, low partial discharge, low noise, high strength against short circuit, and high reliability in service. Its outstanding performance has won high reputation throughout China, and the world, and are highly appreciated by experts of the circle. Transformers can be made with welded tank cover and/or flange , Thus obviated from the necessity of lifting out the active part for inspection after arrival on site.
Partial discharge level:
apparent discharge < 80pC at 1.5 times rated voltage.
Noise level :
below 58 dB for transformers 63MVA and below with AN cooling
Losses:
no-load loss 30% lower than specified by GB/T 6451-1995
Reliability:
no damage or oil leakage have been found in transformers in service up to the present
Short-circuit withstand capability:
Our SZ9-31500/110,SSZ-50000/110 transformers successfully passed short-circuit test in National Transformer Quality Inspecting and Testing Center, and in CESI Laboratory of Italy.
Winding
1. Partially interleaved continuous winding is used for HV winding to improve its behavior under lightning impulse, because of its more uniform voltage distribution.
2. All the spacers and vertical strips are rounded at corners, in order to obtain a more reliable insulation structure.
3. Zig-Zag directional flow is provided inside the windings, so that all parts of the windings are better cooled, resulting in lower winding temperature rise, and specifically lower hot-spot temperature, thus the insulation life of the transformer is prolonged.
4. Separate regulating windings are provided for both the 110kV high voltage and the 35kV medium voltage side, so that a more balanced ampere-turn is obtained in spite of tap-changing, the short-circuit withstand capability is thus promoted. Radially, the windings of a phase assembly are tight-fit, little space is left between the core and the low-voltage cylinder, and between the windings. All the vertical strips and cylinders are thoroughly dried before assembly, so that a tight phase assembly can be finally obtained.
Core
1. High permeability grain oriented high quality cold-rolled sheets are used for the fabrication of core. The sheets are cut on automatic cutting line made by Georg Co. of Germany or Soenen Co. of Belgium. The burrs are controlled within 0.02mm.
2. The core is stacked without stacking the upper yoke, the upper yoke sheets are placed into position after the winding blocks are mounted on the core. The joints of the core sheets are mitred 45fpjoint with step-lap. The stacked core is pressed under even pressure and the edge of the sheets are painted with epoxy resin, so that a straight, robust, integral structure is obtained, helping to reduce core loss and noise.
3. Wooden strips are driven into the space between core and LV cylinder. The yoke is kept tightened by epoxy-resin impregnated glass tape, while the lower yoke is pressed against the wall of the lower tank through threaded bolts. The active part of the transformer is in addition kept in position by devices at three places between the upper yoke and the tank cover in such a way that the active part cannot be displaced during transportation.
