First, appearance
Smooth and round, uniform color, insulation rubber and copper core is not easy to peel off, poor rubber look thick, but when squeezed, the extrusion will become white, easy to fall off in the future cause leakage.
Second, eccentricity
The thickness of the rubber ring is the same, that is, if the copper core is in the middle of the wire, the eccentricity is low.
Third, flame retardant
Using a lighter to burn rubber, when the lighter leaves the wire, the wire should be extinguished automatically, and a small amount of white smoke is emitted. If the flame spreads, releasing a large amount of white smoke indicates that the rubber is of poor quality.
Wire and cable purchase
Graphite Electrodes mainly use needle coke, petroleum coke, as raw material, coal pitch as binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, Graphite Electrode with low resistivity, graphite electrode good conductivity, graphite electrode low ash, graphite electrode uniform and compact structure, good oxidation resistance, high mechanical strength, etc.
Low Consumption,Rp 350 Graphite Electrode,Graphite Electrode Rp 350Mm,For Sell Graphite Electrode
