Product Feature
Equipped with the high-quality nylon pulleys and the sealed bearings for smooth, stable cable movement, this MARSHINE Hold Down Transmission Stringing Block can be a good choice for linemen to deal with the long distance works. Its frame is made of high-strength alloy steel, can withstand the harsh construction environments and the heavy loads. It is able to prevents the conductors from lifting or bouncing during threading, and ensures the precise alignment and tension control. Been designed for the quick and stable attachment to the towers, poles or structures in the harsh construction conditions, its smooth-spinning roller can minimize the cable's friction, and maintain the conductor surface integrity while extend its service life. And the centered alignment can ensures the even tension distribution, which is critical to meeting the sag and clearance standards.
Product Application
Our MARSHINE Hold Down Transmission Stringing Block can be used to guide and stabilize the conductors in 220kV, 500kV and EHV line projects. It is able to applied in the large span areas to keep the conductors aligned during the pulling and tensioning tasks. And it is essential in the steep or sloping installations where the additional control is needed, it is able to keep the conductors in place well. And it facilitates the safe replacement of conductors without disturbing adjacent lines, can secure the conductors during the installation in large span or high voltage projects.
Product Details
The MARSHINE Hold Down Transmission Stringing Block is an essential tool for maintaining the conductor control and stability during the complex stringing operations.
