How to choose a charged insulating shawl

When choosing a charged insulating shawl, the key is to ensure that the shawl provides good insulation, safety and comfort. Here are some important factors to consider when choosing an electrically insulated shawl:

1. Insulation Class

The insulation class of the shawl should comply with international or national standards (e.g. IEC, GB, etc.). Common standards are:

IEC 61482: International Electrotechnical Commission standard for electrical protective clothing for live electrical work.

GB/T 2800: Chinese standard for electrical protective clothing.

Insulation level is usually measured in terms of voltage level, and the rated voltage of the cape needs to be greater than the voltage in the actual operating environment. Common voltage levels are 1kV, 10kV, 20kV, etc.

2. Material

The charged insulating shawl is usually made of high-strength insulating materials, such as:

Rubber: It has very good electrical insulation properties, but may not be as breathable as other materials when in use.

Polyester fibre (polyester): durable and lightweight, but adequate electrical insulation needs to be ensured.

Coated materials: such as polyvinyl chloride (PVC) coated fabrics, which provide good electrical insulation and water resistance.

3. Comfort and Breathability

Comfort for long time wear is very important. Insulating shawls should be breathable to avoid overheating or sweat build-up, and materials with breathable holes or moisture-wicking features are usually chosen.

Consider the weight and softness of the shawl to avoid fatigue caused by prolonged wear.

4. Protective properties

In addition to insulating properties, shawls should be tear-resistant, waterproof and abrasion-resistant to ensure durability and safety for long-term use.

Additional protective features such as fire resistance and UV resistance can also be considered, especially when working in high-risk environments.

5. Compliance with industry standards

Ensure that the cape complies with local industry standards and regulations. For example, when working in China, the shawl should comply with the GB/T 2800 standard; in other countries, the selection needs to refer to the appropriate international standards.

6. Suitable size

The electrically insulated shawl should be selected in a suitable size to ensure that it covers a sufficiently protected area, such as the shoulders and upper body, to avoid the risk of electrical leakage.

Adjustable shoulder straps or other adaptive designs are available to ensure the fit of the shawl.

7. Brand and quality certification

Choose electrically insulated shawls from well-known brands to ensure that their products undergo stringent quality testing and certification.

Some shawls may carry CE marking, UL marking, etc. to indicate compliance with safety standards.

8. Care and Maintenance

Choose shawls that are easy to clean and maintain. Regularly check the shawl for wear and tear and maintain it according to the manufacturer's requirements.

When choosing an electrically insulated shawl, in addition to its insulating properties, consider factors such as comfort, durability, size and compliance with relevant standards. Be sure to purchase according to the actual working environment and safety requirements to ensure that adequate protection is provided during electrical operations.
