Heavy Duty Aluminium Alloy Cable Block Conductor Stringing Block with a Grouding Roller
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.
The earthing pulley pay-off block is a tool specially designed for the construction and maintenance of power lines. Its main function is to provide grounding support for wires when erecting power transmission lines. It usually consists of one or more wheels that are in contact with the ground, thus effectively grounding the wire.
The grounding pulley pay-off block is designed so that the wire can be safely transported while maintaining good grounding, which is essential for the installation and maintenance of power lines. When the grounding wheel is used to pay off the block, the operator passes the wire through the wheel of the block and pulls it by manual or mechanical means, so that the wire moves smoothly on the ground, while ensuring that the wire is always grounded to the ground.
This type of pay-off block is often used in scenarios where wires need to be moved from a higher position to a lower position, such as from the top of a power tower or other support structure to the ground. They can also be used to switch wires from a grounded to an ungrounded state when needed for specific types of maintenance or installation jobs.
The earthing pulley pay-off block plays an important role in the power transmission industry, providing workers with a way to move wires safely and efficiently, thus facilitating the construction and maintenance of power lines.
