According to the position of the human body, live work can be divided into equipotential work, ground potential work, and intermediate potential work. During equipotential operation, the human body directly contacts the high-voltage live parts. The human body in a high-voltage electric field can have dangerous currents flowing through it, endangering personal safety. Therefore, all workers entering a high-voltage electric field should wear a full set of shielding clothing. Live working shielding clothing, also known as equipotential uniform pressure clothing, is made of uniform conductor materials and fiber materials. Its function is to form an equipotential shielding surface on the external surface of the human body in a high-voltage electric field after wearing, thereby protecting the human body from the harm of high-voltage electric fields and electromagnetic waves. The complete set of shielding clothing should include tops, pants, hats, socks, gloves, shoes, and corresponding connecting wires and connectors. Quality requirements: The material and finished product quality technology of live working shielding clothing should comply with the standard provisions of GB 6568.1-2000. (1) The shielding efficiency of type A and C clothing shall not be less than 40db, and the shielding efficiency of type B clothing shall not be less than 30db. (2) The resistance of the new fabric should not exceed 800m Ω; After 2 minutes of spark resistance test, the carbonization damage area of the clothing material shall not exceed 300m ㎡ (3) The fusing current of Type A clothing shall not be less than 5A, and the fusing current of Type B and C clothing shall not be less than 30A. (4) (4) The air flow through the fabric shall not be less than 35L/(㎡ * s); After 500 friction tests, the resistance of the clothing material shall not exceed 1 Ω, the shielding efficiency of type A and C shielding materials shall not be less than 30db, and the shielding efficiency of type B shielding materials shall not be less than 28db. (5) The longitudinal breaking strength of conductive fibers shall not be less than 343N, the longitudinal breaking strength shall not be less than 294N, and the elongation at break in both directions shall not be less than 10%; For conductive coating materials, the longitudinal breaking strength shall not be less than 245N, the weft breaking strength shall not be less than 245N, and the elongation at break in both directions shall not be less than 10%
