With the continuous growth of global electricity demand and the continuous expansion of power transmission and distribution networks, power line construction has put forward higher requirements on the performance and reliability of components. In this context, preformed power fittings have become an indispensable and important part of power engineering with their superior performance and convenient installation methods. Among them, preformed conductor dead endand preformed helical suspension clamp, with their unique structural design and wide applicability, have successfully met the stringent requirements of various power transmission and distribution systems, providing a strong guarantee for the stable operation of the power grid.
Preformed conductor dead end is mainly used for fixing and tension adjustment of conductors at the terminal position of pole towers. Its design not only has excellent tensile strength and can withstand the huge tension in line operation, but also has excellent conductivity and reduces power loss. Preformed conductor dead end adopts a preformed structure, which can minimize the wear on the conductor and avoid material fatigue caused by over-tight clamping, thereby significantly extending the service life of the conductor and reducing maintenance costs. In contrast, preformed helical suspension clamp is used for the conductor suspension support of the intermediate pole tower, focusing on providing stable bending protection for the conductor. Preformed helical suspension clamp can effectively reduce the vibration and friction of the conductor during operation, greatly improve the operational reliability of the line, and is especially suitable for long-distance transmission lines and complex terrain areas.
With the widespread application of preformed power fittings, it not only significantly improves the construction efficiency and reduces the dependence on on-site professional tools and human resources, but also adds double protection for the safety and stability of power line operation. Looking to the future, as the construction of power grids develops in a more efficient and intelligent direction, this type of efficient and reliable power fittings will show more outstanding technical advantages in new energy grid connection, high-voltage transmission lines and cross-regional power grid projects, becoming an important technical support for promoting the modernization of power systems and contributing greater strength to the realization of global energy transformation and sustainable development.
