Shin or Busbar: Definition, Application, and Differences with Wire and Cable

In the world of electronics, you may have come across the terms “shin” or “busbar,” but you might not have precise information about their applications and significance. This article delves into the comprehensive details of the shin and helps you understand its concept, various types, and applications in electronic projects.

What is a Shin?

A shin is a vital component in electrical systems used instead of cables and wires for power transmission in electrical panels. These components are primarily made of copper or aluminum and have a rectangular or cuboid shape. The current-carrying capacity supported by shins should exceed the rated current of the equipment’s power supply. In simple terms, shins are responsible for collecting and distributing energy in an electrical panel.

When there is a need for transmitting a significantly high current in a power system, shins are used. Different types of shins are classified based on their standard current, and there are also subsidiary shins with lower amperage. To prevent potential hazards like electric shocks, these shins are covered with insulating material.

Analysis of Types of Bends in Busbars

What is the concept of bending in busbars? To maximize the efficiency of busbars in electrical panels, it is necessary to bend their shapes. These bends can be done manually or with machinery and come in various types, which we will introduce below.

Bending in Thickness:

This type of bend is used to establish better connections between adjacent busbar components. The size of the bend in thickness is determined by the distance between two terminals that need to be connected. This bend is done in circular and elliptical forms and requires heating the busbar to achieve the bend properly.

Bending in Width:

Bending in width is used to change the direction of the busbar’s path, and the angle of this bend is usually 90 degrees. This type of bend has the ability to create arbitrary angles.

Rotary Bend:

In this type of bend, the busbar is twisted and turned, used when there is a need to change the direction of the busbar’s surface. This directional change should occur along the axis and parallel to the busbar’s movement.

Step Bend:

This bend is used when two pieces are not parallel, and its purpose is to create electrical connections between two non-parallel pieces.

Busbars are recognized as crucial components in electrical equipment and come in various types that require careful understanding. Let’s continue to explore the types of busbars and their applications.

Phase Busbar:

Phase busbar is a type of busbar, and its electrical capacity should not be less than 150% of the rated current of the main switch supplying power to the panel. This type of busbar is used for distributing phase currents in electrical systems.

Ground and Neutral Busbar:

The ground and neutral busbar is used to connect grounding conductors, installing terminals for grounding operations and bonding. This type of busbar is vital in electrical safety and protection systems.

Tubular Busbar:

Tubular busbar is used for nominal currents exceeding 3000 amperes. This type of busbar utilizes specially designed tubes and efficiently conducts large currents.

Rectangular Cross-Section Busbar:

The rectangular cross-section busbar, usually made of copper, is used for internal installations. This type of busbar, with its rectangular dimensions, is recognized for its aesthetic and practical shape in electrical equipment.
