Yoke Plates for Transmission Line

Yoke plates, these components are key in the installation and support of cables in power transmission and telecommunications systems. The cable plate mounts are specifically designed to ensure that cables are securely held in place (often combined with such mounts and other accessories as clamps) to ensure that cables cannot move during settings and operation.

What is a Yoke Plate?

A metal plate, usually made of steel, aluminum, or galvanized steel, that secures cable to poles, towers, or other support structures. It also serves as a stable anchor for clamps or other devices that hold the cables in place.

What Are 6 Types of Yoke Plates?

There are various designs for yoke plates with different configurations for specific cable installation requirements. Yoke plate selection criteria include cable type, working load, and environmental conditions. Below are the most 6 common types of yoke plates:

1. Single Yoke Plate

What is Single Yoke Plate?

One yoke plate is built to accommodate one cable. It is commonly utilized for securing a single cable to a support mechanism, and is often seen on utility poles and transmission towers.

Applications:

• Utilized in power and telecommunications systems for the support of single cables.
  

• Widely used for low-voltage and medium power lines.

Features:

• Design was simple and low cost.
  

• Material: Usually constructed from galvanized steel or aluminum to resist corrosion.

• This can be used with most any clamp to hold the cable.

2. Double Yoke Plate

What is Double Yoke Plate?

A double yoke plate is for holding two cables next to each other. This doubles as necessary in parallel cabling for its installation in certain segments, like Aerial Bundled Cable (ABC) networks or double-circuit power lines.

Applications:

• Commonly used in overhead power lines like for ABC cables.

• It is often used in telecommunications systems where multiple cables are stacked on a common structure.

Features:

• Reducing installation time and hardware cost by supporting two cables simultaneously.

• Much better weight distribution than single yoke plates.

• Commonly used in a high-voltage transmission and fiber optic installations.

3. Adjustable Yoke Plate

What is Adjustable Yoke Plate?

An adjustable yoke plate allows you to set the distance between the two yokes closer together, which is typically used for a cable of smaller diameter, or further apart for larger cables, or an installation where closer yokes are needed. The yoke plate can cater for an extensive different cable diameters, making it useful for installations where cables are likely to be changed in the future.

Applications:

• Compliance Plan: Used in systems that may replace or upgrade their cables in the future.

• Prevalent in regions with multiple sized cables and tensioning.

Features:

• Different cable types can be set to mount using adjustable parts.

• Allows cable layout and configurations as per requirement and flexibility.

• Assists with multiple cable types and sizes.

4. Dead-End Yoke Plate

What is Dead-End Yoke Plate?

A dead end yoke plate is for use at the cable end when the cable must be high-tensioned and anchored. Commonly used on end-pole setups, or in other applications where needing to anchor cables without the need to further tension them.

Applications:

• Commonly used for transmission and distribution lines.

• Typical for end-point applications where the cable is terminated.

Features:

• Capable of taking the full weight of a cable at the end of a span.

• Give a stronger hold on high resistance wires.

• Commonly used for long high voltage or span installations

5. Suspension Yoke Plate

What is Suspension Yoke Plate?

A suspension yoke plate supports webless cable along the length of a span, not the ends. It keeps the cable hanging freely, and works commonly with tension clamps, placing weight over several points of the cable.

Applications:

• Used in supporting cables over long overhead spans

• Common in transmission lines where multiple towers(poles) are used to carry the cables.

Features:

• This will keep cables free-hanging without high tension at the points of attachment.

• Aids in distributing weight equally along the span of the cable.

• For moderate tension application with evenly distributed load.

6. Composite Yoke Plate

What is Suspension Yoke Plate?

A composite yoke plate is made from non-metallic materials, like fiberglass or polymer composites, to decrease weight and enhance resistance to corrosion. These plates are gaining popularity thanks to their improved performance in rugged settings, including coastal or humid regions.

Applications:

• Best for coastal and humid environment.

• Specialized use category such as telecommunications and power transmission but with weight reduction and corrosion resistance and priority.

Features:

• Corrosion, UV and environmental degradation resistant and light.

• Features Designed for Extreme Conditions

• It’s often a little bit pricier upfront, but more durable and creates less maintenance over time.

Cable installation yoke plates are leveled components to fix the cables at a specific place where the cable needed stable support and anchorage. With their durability, versatility, and ease of installation, they are an essential element in power transmission, telecommunications, and industrial cable systems. This not only allows for consistent and optimal power delivery but also improves longevity, ensuring peak performance throughout the system while minimizing wear and tear.
