Guy Wire Manufacturer

TTF power manufactures and supplies hot-dip galvanized guy wire for overhead power transmission and distribution systems. A guy wire is a tensioned cable that was originally called “gei” from the Dutch who used it to fix ships masts. It is now called guy wire, stay wire, guy strand, guy cable, guy anchors and sometimes guide wires. It is a tensioned cable, wire or rope that is used to steady, guide or secure all structures like ship masts, electric poles, radio towers or wind turbines. All these structures are of some considerable heights that are not self-supporting. The guy wires work by distributing some of the structures weight to the ground.

The electricity systems, telecommunications, and broadcasting industries can all employ man wires. It is positioned at an angle along a diagonal line that is anchored to the ground. It is fastened to a concrete ground anchor that serves as a support for multiple guy wires.

Due to the wind force in the location, guy wires are typically needed when the construction is higher than 20 feet. They aid in preventing these tall buildings from toppling, twisting, or breaking. Every city and nation has its own requirements for installing guy wires, thus seeking professional advice before installation is advised.

Construction of guy wire

The guy wire can be divided into various divisions that help to describe the best guy wire. These are as discussed below. Other features of a good guy wire state that it should be lightweight, have good design, have a little stretch, should be durable and have high break strengths to withstand great tension.

  1. Material — the materials used to make the guy wires are important in assisting them to be durable by resisting different weather conditions. The materials should be pure and quality steel and should be coated by zinc.
  2. Stranding — the wire strands should be covered in the wires known as 7-wire of 19-wire strands.
  3. Tension and design — the guy wire should have a high tensile strength that helps it to prevent breaking and be resistant to all weather conditions that allow it to increase the service life of the guy wire.
  4. Weight of the coating — the guy wires should be coated in zinc per ASTM A475 standard, and the weight is determined by the evaluation based the various test methods.
  5. Finish — the zinc-coated wire is free of flaws that are not in consistent with industrial standards. The zinc coating is constant and of reasonably uniform thickness.

Applications of guy wire

The guy wires as previously stated can be used in power systems, telecommunications, broadcasting and ship masts. The various ways they are used are as discussed below.

  1. Power systems — power systems use utility lines that run for long distances with many utility poles which need to cross many places. These connections cause a lot of tension between the different poles, guy wires are connected from the pole to the ground to support the unstable loads and make sure the structures are straight and prevent the ground from moving. A guy wire is used with guy set, which is insulated to avoid shock in case of contact with the human skin.
  2. Telecommunications and broadcasting — the guy wires can be used to support the telephone pole or antenna mast. They are similar to the ones used for the power systems.
  3. Sailing — the guy wires can be used to support the masts of the ship for easier sail. The guy wires are made of stainless steel that helps it resists rust especially from frequent contact with water.

Functions of guy wire

The guy wires basically support the height of the poles or structures that are high standing to add stability and prevent falling, bending or breaking of the poles. This also offers safety by keeping the structures erect from the strong winds or storms that may affect the structures. The guy wires also help construction to use higher limits which may be lower due to the absence of the guy wires. They are used in a diagonal line from the post or tower to provide maximum stability and they are made from galvanized stainless steel that helps to reduce corrosion and rust while also preventing electrocution.

Guy wires are tensioned cables, ropes or wires that are used to steady, guide or secure all sorts of tall buildings and structures that are not self-sustaining. The use of the guy wires provide stability and prevent bending, breaking and even falling of the tall buildings. They can be used on the power systems, telecommunications and broadcasting. They were initially used in providing support to the ship masts to help in sailing. They are installed at an angle far from the post or tower in a diagonal line which helps to distribute the unbalanced load in the overhead lines.

The guy wire is also known as guy rope, guy strand, or stay wire. They are made from galvanized steel, or stainless steel which helps them to resist the harsh weather conditions such as rain, storm, winds and high temperatures. Insulated guy wires are made of a finish that helps them to prevent electrocution in case of contact with the human skin. Braided guy wires have high tensile strength that prevents them from breaking and other physical stresses. They are also used in electric systems, radio towers, wind turbines and in ships masts for sailing.

Stay insulator

A stay insulator used at a stay wire is at high pressure so that the tension on the cable is transformed into a force. This helps to prevent current from flowing to the unwanted places.

Stay rod

The stay rods are used with the guy wires in tower construction and electric poles at the linked part to prevent them from falling under stress.

The installation of the guy wire is quite easy and requires little technical skills but they should be done by professionals. Other fittings to be used with the guy wire such as guy grip, guy clamp or guy thimble should be prepared before the installation. The first step is to connect the one side of the three or four guy wires to the top of the structure. They can be twisted on or attached to the mounting bolts. The other side of the guy wire is attached to the points on the ground. The cables should be tightened to prevent them from moving. The cables should also be mounted far from each other.

Quality tests on guy wire

Before the guy wires are released into the market, they have to undergo a series of tests and inspections in order to verify their security and ease of use during and after installation. These tests and inspections are as discussed below.

  1. Lubrication inspection – the guy wire should be examined and lubricated with the specified equipment, both the essential and the outer boundary. This inspection is done during manufacture.
  2. Tension inspection – before the delivery of the equipment, the manufacturer should perform the workload capability tests to check the current condition and strength of the cable.
  3. Tension breaking strength – this should be done before the installation by the engineer. This ensures that the wires meet the terms with the tension breaking strength limits.
  4. Rope periodical inspection – this inspection is done after installation and it checks the extreme broken wire, alteration, severe corrosion, decrease in the outer wire diameter and damaged or exiled clamp, thimble or anchor.

Stranding of guy wire

The guy wires are categorized according to the type of stranding that is used to make the wire or rope. The major stranding for the guying products are mainly two types which is 1*7 stranding and 1*19 stranding. These stranding have one major core for added stability.

  1. 1*7 stranding – these are made of galvanized steel and it is used in guying applications such as towers, antenna and other tall structures that are placed from the top to the ground. They include the use of seven strands that are twisted together to make the rope. They should be installed or used in areas where rare bending will occur.
  2. 1*19 stranding – these are also galvanized strands that are also used in guying the free, high- standing structures. The galvanized steel helps to prevent corrosion and rust. They use the twisting of the nineteen strands to make the guy wire with one central core. They have lower breaking strength than the seven strand wires. They are also used in supporting and adding stability to the antenna, towers and other tall structures. these
