• Potential Equalizing Clothing -- Essential “Artifact” for High Voltage Work Protection and Safety”　

  • Darui Electric recommends for you

  • 　Potential Equalizing Clothing is made of metal wires and is an essential safety protection device for live high-voltage operations. Currently, uniform voltage generation is limited to live working below 220kV, and the surface resistivity of the uniform voltage from head to toe does not exceed 10Ω. During equal-potential live maintenance, workers must wear qualified suits, socks, gloves, and hats, and ensure that the connecting parts are firmly connected. Uniform voltage clothing is mainly used for shielding and cannot be used as grounding protection. The following points should be noted for its selection and use:
     

     


    1. When selecting Potential Equalizing Clothing, pay attention to the surface resistivity. The resistance from gloves to socks must not be greater than 10Ω. Choose products with good shielding and shunting effects and resistance to sparking.
    2. Before using pressure-uniform clothing, the appearance quality must be carefully inspected. Once any defect is found, it will no longer be used. If contaminated by dust, it must be cleaned. When the metal wires are oxidized or broken due to washing or other reasons, the shielding and shunting effect will be affected, and the pressure-uniform protective clothing will not be used.
    3. When wearing, the multi-strand wires of clothing, hat, gloves, socks, and other parts must be connected to each other in the specified order to ensure good contact. At the same time, these wires cannot directly contact the skin and should be separated by underwear, especially on the neck. Synthetic fiber fabrics should not be used for underwear, not only because of poor heat dissipation but also to prevent electric sparks caused by short circuits, which can cause the fabric to burn and stick to the skin, expanding the burn degree and aggravating skin injury.
    4. During equal-potential operation, when connecting wires, parallel wires with sufficient current-carrying capacity must be selected, and good contact must be ensured. Grounding protection is strictly prohibited.
    5. After wearing Potential Equalizing Clothing, it should be carefully removed to avoid damage, and kept dry and clean. It should be stored with as little folding and friction as possible. It should be hung on a hanger and placed in a special wardrobe. The storage place must not have dripping, moisture, or simultaneous storage with pollutants, so as not to affect the protective quality of the uniform pressure clothing.
