OPGW Optical Ground Wire
OPGW Optical Ground Wire
Stranded Unit Type in The Eccentric Inner Layer Of Cable
Optical ground wire (OPGW) is a dual functioning cable. It is designed to replace traditional static/shield/earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. OPGW must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors such as wind and ice. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside the cable.
The OPGW cable design is constructed of a fiber optic core (with multiple sub-units depending on the fiber count) encased in a hermetically sealed hardened aluminum pipe with a covering of one or more layers of steel and/or alloy wires. Installation is very similar to the process used to install conductors, although care must be taken to use the proper sheave or pulley sizes so as not to cause damage or crush the cable. After installation, when the cable is ready to be spliced, the wires are cut away exposing the central aluminum pipe which can easily be ring-cut with a pipe cutting tool. The color-coded sub-units are preferred by most users because they make splice box preparation very simple.
Product Features
Preferred option for easy handling and splicing.
Thick-walled aluminum pipe (stainless steel) provides excellent crush resistance.
Hermetically sealed pipe protects optical fibers.
Outer wire strands selected to optimize mechanical and electrical properties.
Optical sub-unit provides exceptional mechanical and thermal protection for fibers.
Dielectric color-coded optical sub-units are available in fiber counts of 6, 8, 12, 18 and 24.
Multiple sub-units combine to achieve fiber counts up to 144.
Small cable diameter and light weight.
Obtaining appropriate primary fiber excess length within stainless steel tube.
The OPGW has good tensile, impact and crush resistance performance.
Matching with the different ground wire.
Applications
For use by electric utilities on transmission lines in lieu of traditional shield wire.
For retrofit applications where existing shield wire needs to be replaced with OPGW.
For new transmission lines in lieu of traditional shield wire.
Voice, video, data transmission.
SCADA networks.

OYI-ATB04B Desktop Box
OYI-ATB04B 4-port desktop box is developed and produced by the company itself. The product’s performance meets the requirements of industry standards YD/T2150-2010. It is suitable for installing multiple types of modules and can be applied to the work area wiring subsystem to achieve dual-core fiber access and port output. It provides fiber fixing, stripping, splicing, and protection devices, and allows for a small amount of redundant fiber inventory, making it suitable for FTTD (fiber to the desktop) system applications. The box is made of high-quality ABS plastic through injection molding, making it anti-collision, flame retardant, and highly impact-resistant. It has good sealing and anti-aging properties, protecting the cable exit and serving as a screen. It can be installed on the wall.

Galvanized Brackets CT8, Drop Wire Cross-arm Br...
It is made from carbon steel with hot-dipped zinc surface processing, which can last a very long time without rusting for outdoor purposes. It is widely used with SS bands and SS buckles on poles to hold accessories for telecom installations. The CT8 bracket is a type of pole hardware used to fix distribution or drop lines on wooden, metal, or concrete poles. The material is carbon steel with a hot-dip zinc surface. The normal thickness is 4mm, but we can provide other thicknesses upon request. The CT8 bracket is an excellent choice for overhead telecommunication lines as it allows for multiple drop wire clamps and dead-ending in all directions. When you need to connect many drop accessories on one pole, this bracket can meet your requirements. The special design with multiple holes allows you to install all accessories in one bracket. We can attach this bracket to the pole using two stainless steel bands and buckles or bolts.

Non-metallic Strength Member Light-armored Dire...
The fibres are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. A FRP wire locates in the center of core as a metallic strength member. The tubes (and the fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE (LSZH) outer sheath.(WITH DOUBLE SHEATHS)

Wire Rope Thimbles
Thimble is a tool that is made to maintain the shape of a wire rope sling eye in order to keep it safe from various pulling, friction, and pounding. Additionally, this thimble also has the function of protecting the wire rope sling from being crushed and eroded, allowing the wire rope to last longer and be used more frequently.
Thimbles have two main uses in our daily lives. One is for wire rope, and the other is for guy grip. They are called wire rope thimbles and guy thimbles. Below is a picture showing the application of wire rope rigging.
