500KV screen clothes for live working
500KV screen clothes for live working
Main function:Human body will in direct contact with the high-voltage live parts when equal potential working. There will be dangerous current flows in the high-voltage electric field, endangering human body. By wearing a full set of shielding clothing (equipotential voltage-sharing clothing) can guarantee the personal safety of staff. Parts of the clothing are securely connected by convenient movable joints to form a good conductive system, these components are connected with the connector, that is, coat, gloves and pants connection, pants, socks and shoes connection, so that the human body and high voltage equipment environment becomes to equipotential, using this principle, play the role of shielding;
Applicable industries & positions:
Industries: power Grid Live Working Center (500KV EHV);
Positions: personnel engaged in AC voltage 110KV-500kV high-voltage equipment.
Features & Introduction:
◆The protective performance conforms to the Grade protection standard of the screen clothing for live working;
◆Excellent and reliable electrical and flame retardant properties, anti-static, anti-UV, anti-fouling, anti-moth, anti-bacterial, deodorant, high-pressure shielding performances;
◆Good flame retardant performance, no open flame after ignition, the combustion zone does not spread and rapid carbonation; flame retardant aramid fiber and metal fiber has good conductive property, folding, strong elasticity and corrosion resistance;
◆High screen efficiency, small surface resistance, high discharge capacity, good flame retardant, cloth smooth, excellent quality, durable, warm in winter and cool in summer;
◆Have the characteristics of washable, antifriction, colorfast, good tensile, not easy to tear, long service life, etc.;
◆Clothing sewing thread, zipper, button, pocket cloth and other accessories are made by flame-retardant materials, better safety performance;
◆The buttons and other related accessories are made by flame-retardant materials.
◆Should follow the corresponding safety rules and regulations. it is strictly forbidden to short circuit the grounding current, no-load circuit and the capacitive current of the coupling capacitor through screen clothing;
◆Multi-strand metal cables, which in clothing, cap, gloves, socks, shoes and other parts, must be connected in order when worn, but not in direct contact with the skin. Should wear underwear, but no synthetic fabric, to prevent arc sparks melting, adhesion to the skin and expand the burn area, aggravating injury;
◆Besides the regular preventive experiments, screen clothing needs a visual inspection about the reliability of every connector before live working, and an on-site measurement of the resistance of the whole garment by multimeter after wearing. Tests mentioned should be qualified before clothing using;
◆For broken and damaged screen clothing, screening efficiency test should be carried out, and forbidden to use it if it doesn’t meet the standard requirements;
◆Only wear when working at equipotential or near high voltage to prevent induced voltage;
◆Screen clothing should be properly storage, and dedicated in general. Should be put in packing bag/carton after folding, and stored in a live working warehouse;
◆Since conductive materials in conductive fabrics will be oxidized in the air, the screen clothing must be packaged so that it will not be oxidized after long-term storage.
