What Is an Insulation Cover?
Insulation covers are safety protective covers used to insulate and protect the charging section of fixtures, the wiring section, and the exposed charging section of high-voltage overhead distribution line clamps.
There are three types of covers: a one-touch push type that is pushed into an outlet, a type that is fitted by passing an electric wire through it, and a heat-shrink type that is covered over the charging section of a fixture and shrunk by a hair dryer or the like. Types that are used by cutting them according to the length of the terminal block.
Since they are safe and protective goods, it is important to select the appropriate cover for the applicable part, considering the material, terminal block standards, outer diameter of the applicable wire, operating voltage, insulation resistance, and other factors.
Uses of Insulation Covers
Insulation Covers are widely used in electrical work, machine repair, maintenance of construction equipment and machinery, communication equipment, home appliances, automobiles, motorcycles, etc.
Examples of use are as follows:
- Installation of solar panels
- Wiring with bare crimp terminals
- Wiring of driving chargers
- Cable maintenance
- Wiring work in a panel
- Protection of connections for small basic switches
- Wiring of home appliances, electronic circuits, machines, etc.
- Preventing grounding electric shock accidents by attaching to armbar, HCF, etc.
- Protection of low-voltage switchgear
- Grip protection for extended wires
Principle of Insulation Cover
Insulation Covers made of ABS resin, polyolefin, etc. are used for medium-voltage power supply connections and conductor connections of less than 300 V, such as charging sections, joints, bolt sections, support connections, etc. of one-touch push type for outlets and simple structures.
Heat-shrinkable tubing is also available, in which the charging and wiring parts of the device are covered so that they are not exposed, and then heat-shrinked with a gas torch, industrial dryer, etc.
The applicable current for the heat-shrinkable tube specification is 100A, and the voltage is 600V. The insulating cover that protects the tip of the power cable with the terminal from short circuits is made of 0.4 mm thick polyurethane with a double structure and a solid adhesive treatment. Not too hard, not too soft, it has an exquisite hardness, so it feels good to use, and is transparent so you can check the polarity and phase of the cable.
Terminal insulating covers such as battery terminal insulating rubber covers are made of flexible PVC material. The red and black colors help prevent accidental shorts and improve the appearance of your wiring.
Widely used in communication equipment, home appliances, automobiles, motorcycles, etc. Insulating covers for high-voltage distribution lines such as steel towers for transmission lines, dead-end clamps for high-voltage overhead distribution lines, sleeve and connector connection points, branches for low-voltage overhead distribution lines, and wire connections for secondary terminals of pole transformers.
Polyethylene, which has high insulation, flexibility, durability, and weather resistance, is mainly used.
Covers designed with the shape and structure appropriate for each usage area can be used to improve work efficiency.
