Secondary Clevis for Utility Pole-The Complete Guide

Among the many overhead pole line accessories that you must buy, one of them is a secondary clevis. It has various critical roles that it plays on any pole line or transmission line as many prefer to call it.

Are you planning to buy secondary clevis in China? Whether the clevis will be used on your pole line project or you want to buy bulk secondary clevis for sale, it is important to ensure that you choose the best.

Read on as I guide you on how to find premium secondary clevis.

What is a Secondary Clevis for utility poles?

A secondary clevis is a D-shaped pole line accessory onto which you can connect other components of the transmission line. The clevis has a pin that passes through the holes that are at its very end.

The pin is usually supported to its respective position by a clevis bolt.

This is why a clevis is always referred to as a connector as it connects many other components on a pole line.

Secondary clevis is also referred to as dead-end clevis or you can simply call it a dead end bracket.

What are the uses of Secondary Clevis?

When planning to buy secondary clevis, there is a likelihood that you already have something in your mind. For someone who is not fully aware of the uses, it is our duty to help you know.

Since clevises are mainly used as a connector, we shouldn’t have different expectations when it comes to a secondary clevis. Some of its uses include;

Connecting to a spool insulator: 

A spool insulator on a pole line is used for insulating and supporting the secondary conductors. An how is this insulator attached to the pole? This is the work of a secondary clevis.

Balancing strains:

A secondary clevis that has large eye nuts can play an important role in balancing the strain on the conductor especially at the corners. This helps to ensure that the conductor does not snap or break in specific areas.

Stringing the conductors:

An overhanging conductor on a pole line can be a safety risk. A secondary clevis can minimize this by acting as a stringing pulley hence providing a point of attachment for the conductor.

Minimizing turning resistance:

Apart from acting as a point of attachment, the secondary clevis cuts out the turning resistance of a conductor. This is possible mainly because of its raised design.

Types of Secondary Clevis

Secondary clevis for pole line come in different designs and styles. The differences ensure that they suit perfectly in their specific areas of application.

Types of clevis include:

1. Deadend Secondary Clevis

This type of secondary clevis has slotted holes that allow easy installation without causing any disruption to the insulator.

2.  Swinging Secondary Clevis

The swinging secondary clevis is usually used with an angle bracket. This type of secondary clevis helps to minimize strain at the corners thanks to its flexible mounting mechanism.

The clevis can be installed on the electrical cross arm to provide insulation on the dead-end assembly.

3. Extension bracket with clevis

Majorly used in rural applications where it is possible to achieve desired spacing with on the secondary clamps.

4. Clevis type Wire holder

The wire holder secondary clevis clamp is mainly used with specific spool insulators.

The clevis attaches the insulators on pole lines where triplex-type cables are used.

Components of a Secondary Clevis

Different types of secondary clevises, the components of some differences.

1. Clevis

The clevis is the main body of a secondary clevis, there are different of sharps. The most common are D and U sharps. The clevis tends to assume a D-shape, so the is also secondary clevis is also called D Iron clevis.

2. Clevis Pin

Clevis pin is used to string a spool insulator and prevent the insulator and the clevis from moving relative to each other. The pin can either be threaded or unthreaded.

3. Cotton Key

The cotter pin is used to secure a clevis pin in place.

4. Angle Bracket

The angle bracket is only used with the swinging secondary clevis, and fix the clevis to the pole line.

 Specifications for Secondary Clevis

If you are intending to buy a secondary clevis fastener that will not fail you, it is important that you focus on its specifications. They give details of what you should expect from pole line fitting.

Here are some of the physical and technical specifications of secondary clevis that you should know:

Secondary clevis material

A secondary clevis is expected to be strong and rigid enough so that it can sustain the strain from the spool insulator. This requires that the material should be strong enough.

Steel is the main material that is used for manufacturing the clevis for the pole line. It is chosen due to its high tensile strength.

Steel is further hot-dip galvanized so that it can have protection against corrosion and abrasion.

Secondary clevis dimension

The dimensions dictate the size of the secondary clevis. They are usually denoted in inches.

Secondary D iron brackets come in different dimensions. Before you choose any single clevis, see if its dimensions match with your pole line requirements.

Some of the key dimensional aspects that demand your full attention include the size of the clevis bolt, clevis pin size, and the hole size.

You should also consider the diameter of the mounting hole.

Secondary clevis fastener

When buying a secondary clevis for pole line, you should check if it comes as a whole package of the fastener.

This package comprises a clevis, clevis pin, and a tang.

The three components are connected when installed onto a pole line.

Secondary clevis finishing

Since a secondary clevis will be exposed to all vagaries of nature, it should have a protective finishing.

The most ideal finishing is a galvanized coating. It protects the clevis from rust, excess heat, and other elements that can have negative effects on the clevis

Secondary Clevis Manufacturer in China

After equipping yourself with all the necessary knowledge about secondary clevis, what next?

Your next move should be finding a reliable secondary clevis manufacturer in China. This is the surest way of ensuring that you get a utility clevis that will meet your ultimate pole line needs.

Before you choose a manufacturer, start by confirming the price of the secondary clevis. Find out if the price includes the secondary clevis accessories for installation.

You can then read several secondary clevis reviews to see what other people think of the dead-end clevis from a particular manufacturer.
