Heat Shrinkable Two-color Tubes

Heat shrink two color tube is a type of heat shrink tubing that changes color when exposed to heat. These tubes are often used to insulate wires, protect them from abrasion, and provide strain relief.

The two color design of these tubes allows for easy identification of wire connections. When heated, the tube shrinks to conform to the wire and has a color change that indicates a secure connection. There are different types of heat shrink two color tubes available such as red and black, blue and yellow, etc, and they come in varying sizes and shrink ratios.

There are heat shrink two color tubes that come in green and yellow color combination. This type of tube is often used to identify the grounding wire in electrical wiring applications, as per the international color code. The green and yellow color combination indicates that the wire is grounded, ensuring safety in electrical circuits.

Just like other heat shrink two color tubes, the green and yellow two color tube shrinks when exposed to heat, providing excellent insulation and strain relief to the wire beneath it. It also has an indicator that changes color when it shrinks, making it easier to tell when the tube has adequately shrunk.

Here are the steps to install a heat shrink two color tube:

Choose the correct size of the tube that will fit the wire you want to insulate.

Cut the heat shrink two color tube to the appropriate length, allowing for enough material to overlap the wire ends.

Slip the tube over one of the wire ends and move it down the wire until it completely covers the connection point.

Use a heat gun or a lighter to apply heat to the tube, starting at one end and moving to the opposite end. Continue until the tube has fully shrunk and adhered to the wire beneath it.

Make sure that the color change indicator has been activated, indicating that the tube has shrunk to the correct size and providing a secure connection.

If needed, repeat the same process with additional tubes on the other wire connections.

Inspect the work to ensure that the connections are well insulated, and the color of the heat shrinks has changed to indicate a secure connection.

By following these steps, you can install a heat shrink two color tube and ensure that your wires are properly insulated and protected from damage.
