Product Description:
The Double Pulley Replace Roller plays a pivotal role in the
replacement process of old earth wires with new OPGW cables. The
installation of rollers is done while stringing OPGW on a live
line, with a distance of 10-15 meters on the pulling rope. The
primary function of these rollers is to rotate the old ground wire
with new OPGW cable during the replacement process without any
loosening or vibration.

Features:
Assuming the live line condition of overhead transmission lines,
Double Sheave Replace Rollers offer an effective means to replace
old earth wires with new OPGW cables. To meet the varying needs of
our customers, we offer diverse designs and materials.
Technical Parameters:
The OPGW HANGING ROLLER is a product commonly used in the power
industry. It is made of MC nylon wheels, which have lightweight
properties, enhance wear-resistant capabilities, and do not cause
any damage to the wire.
Aluminum wheels are also used for this product; however,
customization is required for manufacturing. The preference for MC
Nylon wheels is due to their superior properties in the context of
their affordability and efficiency.
Applications:
For the installation and maintenance of OPGW (Optical Ground Wire)
cables on transmission lines, specialized equipment known as OPGW
double sheaves support rollers is used. These support rollers have
dual sheave design that is used to support and guide OPGW cables.
They come with smooth-rolling bearings that minimize cable friction
and have protective liners to prevent cable damage.
OPGW double sheaves support rollers are typically manufactured
using lightweight and durable aluminum alloy. These rollers are
used for cable stringing operations, temporary support during
installation, protecting OPGW from damage during pulls, and
maintaining proper bend radius.
During installation, OPGW double sheaves support rollers must be
correctly positioned on support structures, properly rated for
cable weight, and regularly inspected for their condition. Proper
alignment is essential to prevent cable stress.
