The cross-sectional degradation of steel transmission tower members due to corrosion has been one of the major issues in the transmission line system. The degradation of appearance of the material has also been seen because of corrosion. Therefore, there is a need for a less corrosive and high strength alternate material for transmission towers. It seems in recent years that alternate materials have been needed to replace steel which have low maintenance cost and good resistance to corrosion. The advantages of composite transmission towers are fire resistant, high stiffness, durability, high strength, moderate ductility, rigidity, easy to assemble and economical. The present study has made an effort to evaluate the performance of composite transmission tower. The glass fibre polyamide composite material has been used as a structural material. First, a finite element tower model of 132 KV has been set up in Structural Analysis and Design Software as glass fibre polyamide structural material as per transmission tower design guidelines (Code for Transmission tower design, IS 802.1.1.1995, Bureau of Indian Standards). Second, all the active loads like wind load on the body, wind load on conducting wires and ground wires, weight of conducting wires, weight of structure, weight of ground wires, weight of insulator and weight of line man with tools are calculated manually as per transmission tower design guidelines and applied in the finite element tower model. The stress distribution of the composite tower model has been simulated in Structural Analysis and Design Software and the results have been analysed. The broken wire condition (if one conductor is broken or earth wire is broken) has been innovatively considered in the present study. Results obtained in this article show that maximum induced stress on transmission tower member is less than the deign strength of glass fibre polyamide composite material. The glass fibre polyamide composite material has been found to be capable to withstand the maximum stresses induced due to different loading conditions considered in the study.

“…In order to prevent conductor cross-arm fro m bending and narrowing the safety gap excessively, foam-filled hollow tube is used for cross-arm to improve its flexu ral rigid ity, wh ich makes up for its deficiencies of small elastic modulus and large deflection effectively [6] . And increase FRP insulators rods, which is fixed to the pole via metal hoops [7,8] . Meanwhile, to prevent pollution and lightning flashover, silicone rubber sheath dressing with sheds is added to the hollow FRP tube, which will enhance the creepage distance of FRP cross -arm effectively.…”

As an important class of special load-bearing structure, transmission pole affects the security, economy and reliability of transmission lines running directly. With the implementation of domestic major projects in recent years, such as UHV project, smart grid an d transformation of rural grid, transmission pole of composite materials (referring to fiberglass reinforced composites in this paper) becomes one focus of attention in electric power industry for its lightweight, high strength, good electrical insulation, easy maintenance and good environmental adaptability, etc. Based on the existing national code for design of overhead transmission lines, design requirements, research and engineering practical experience, the structure design of a 110kV FRP pole is completed in the paper. S ubsequently, the problem of small elastic modulus and large deflection are solved by mainly considering the pole's structure, material and cross section, etc. Then, the finite element static analysis is carried out in ANS YS. Result shows that the transmission pole meets the requirements of stress and deflection in the national code, which provides a theoretical reference for a further research.

“…Although there are many advantages for the composite TL tower over the metal TL tower [1], [2], it has disadvantages also, such as having none grounding design for the case of lightning protection [3]. The lightning insulation performance for a composite TL tower with double-grounding conductors is analyzed and discussed in [4].…”

In this paper, the transient impulse performances of a 330-kV composite transmission line tower under direct lightning strokes are comprehensively presented. An equivalent distributed parameter model combined with lumped capacitance elements for the tower is established. The wave impedances of the hybrid model are determined by using analytic equations. The lumped capacitances are calculated by 3-D finite element method (FEM). An accurate model for extended grounding structure (EGS) of the tower base considering the soil ionization is used to simulate its impulse performances. The wave process of the tower is analyzed by using the electromagnetic transient program (EMTP). The proper grounding conductor system is determined for the case of a superior lightning impulse performance considering three diverse grounding configurations. The influence of radius of the grounding conductor is assessed. The numerical electromagnetic field analysis, finite-difference time-domain (FDTD) simulation is applied to verify the validity of the presented hybrid model. Then, the influence of the wave-front time of the lightning current, the soil resistivity, the dimension of the EGS, and their combined effect on the transient impulse performances for the EGS are analyzed and discussed.
