Stringing Power Cable Pulley Block with Grounding Roller Galvanized Nylon Sheave Aerial Cable Pulley Block For Conductors
Our grounding roller stringing block, nylon sheave pulley block serves to release the induced current of the conducting wire into earth when applied to conductor stringing construction. Our users can see Large Diameter Stringing Block for other parameters about the block. Also, customers can order other large diameter stringing blocks with grounding roller. Just adding the postfix 'D' to the model of block is enough.
A grounding pulley pay-off block is a tool used in power line construction and maintenance, usually used to suspend wires or ground wires in high-voltage transmission lines. These blocks are designed to have a grounding function to ensure operator safety during construction.
This block usually consists of one or more pulleys connected by a bracket or frame and connected to a rope or wire rope used to suspend the wire or ground of the power line. The bottom of the block is usually designed in a ground shape and can be effectively grounded to prevent the conduction of current through the block to the construction personnel.
The main functions of the earthing pulley pay-off block include:
Suspension wires or ground wires: These blocks are used to suspend wires or ground wires in power lines, ensuring proper installation and maintenance of the lines.
Grounding protection: The grounding design of the block ensures that even if the block comes into contact with the power line during construction, it will not pose an electric shock hazard to the operator.
Reduce friction: The stopper is designed to reduce friction between wires or ground wires to ensure the normal operation and service life of the line.
The grounding pulley pay-off block is usually made of a durable metal material, such as aluminum alloy or steel, to ensure adequate strength and durability. They are widely used in power industry and are one of the important tools for power line construction and maintenance.
