Insulated gloves are a type of electrical safety appliance that protect personal safety and must maintain good performance. Therefore, the following visual inspection should be performed before use: (1) Whether the insulating gloves meet the requirements of the regulations. (2) Whether the insulating gloves are in good condition, whether the surface is damaged and clean or not; if there is dust, it shall be wiped clean; damaged and carbon-imprinted shall not be used. (3) Insulated gloves are rubber products and shall not have defects such as trauma, cracks, loopholes, bubbles, burrs, scratches, etc. If defects are found, they should be stopped and replaced in time. (4) Check that the voltage rating of the insulating gloves matches the voltage rating of the simulated operating equipment. The voltage rating of the insulating gloves should be equal to or higher than the voltage rating of the simulated operating electrical equipment.
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel Bright Bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty
