Stretchable Gold String

The Stretchable gold string is an important component in electric power transmission lines, mainly used for fixing and supporting conductors to ensure the stability and safety of the line. The following are its main features and components:

Function: It is used to fix the conductor, bear the tension of the conductor, and prevent it from loosening or falling off under wind load or temperature change.

Types: Common ones include bolt type, wedge type and compression type, which are suitable for different conductor types and tension requirements.

Function: Connect the strain clamp with the insulator string or other hardware to ensure the stability of the overall structure.

Types: Include U - shaped hanging rings, extension rings, etc., and the specific selection depends on the design requirements.

Function: Provide electrical insulation to prevent current from flowing through the hardware string to the tower.

Types: Common ones are porcelain insulators, glass insulators and composite insulators.

Function: Includes vibration dampers, equalizing rings, etc., which are used to reduce vibration and corona effect and improve the durability and safety of the line.

Installation: It needs to be carried out according to the design requirements to ensure that each component is firmly connected and the tension is evenly distributed.

Maintenance: Regular inspection should be carried out, and damaged components should be replaced in time to ensure the long - term stable operation of the line.

The Stretchable gold string is a key part of the transmission line, and its design and installation quality directly affect the safety and reliability of the line.
