22140-3 application field and working principle is a miscellaneous category that topic covers a wide range of topics and focuses on the application field and working principle of the 22140-3 standard. This standard is applicable to composite overhead ground wire systems and insulators used in the electrical transmission and distribution systems.

The 22140-3 standard covers the design, manufacture, installation, structure and protection of composite overhead ground wire systems and insulators that are used in the electrical transmission and distribution systems, are installed on overhead structures, such as pole lines, cable trays, and aerial structures. This standard also sets the requirements for the composites used in fabrics, poles and other components such as anchoring units, asphalt foundations, joints, and insulators.

The 22140-3 standard covers the design of the composite overhead ground wire systems including pole lines, cable trays, and aerial structures. It includes the design requirements of different system components including the hoisting of poles and/or wires, the protection of lead and/or anchor wires, the installation of transmitters/receivers, and the installation of insulators and brackets. This standard also includes the testing requirements of the composite ground wire systems and insulators.

The working principle of this standard is based on the laboratory testing that has been conducted in order to verify that the composite overhead ground wire systems and insulators are meeting the requirements of the standard. The laboratory tests evaluate the performance of the components including the resistance to breakdown, the moisture content of the composite, the tensile strength of the components, the distortion and deflection caused by bending forces, the mechanical strength of the composite, and the electrical characteristics of the components.

The 22140-3 standard also covers the installation of the composite overhead ground wire systems and insulators. The installation process must follow the instructions given in section 5 of the standard. This process includes various steps including the installation of the steel retainer, the support poles, the driveposts, the anchor line and the hoisting of the components. In addition, the process also includes the assembly and testing of the electrical components, and the installation of the insulated wires

The 22140-3 standard ensures that the components are safe and reliable for electrical transmission and distribution systems. It provides the guidelines for the proper installation and operation of the composite overhead ground wire systems and insulators, and also provides the necessary information required to safely and effectively execute the tasks.

In conclusion, the 22140-3 application field and working principle is a miscellaneous type of standard that covers the application field and working principle of the 22140-3 standard. It sets the requirements for the design, manufacture, installation and structure of the composite overhead ground wire systems and insulators used for electrical transmission and distribution systems. It also provides the guidelines for the installation and operation of the components, and for the testing of the electrical components.
