T1 T2 copper row C1100 C1020 How to tell the difference between the color difference T1 T2 copper row copper copper row Purity environmental requirements T2 copper row conductivity copper row number T1 thermal conductivity copper mine copper row how what specifications of the most appropriate bearing capacity copper row copper row conductive copper casting mold of how environmental T2 copper row copper a relatively pure copper, and can be approximated that is pure copper (99.9%), electrical conductivity, thermal conductivity, plasticity are better. T1 copper with a copper better than T2, thermal conductivity, electrical conductivity ductility and corrosion resistance. T1 copper purity can be achieved (99.99%) copper trace impurities have a serious impact on the electrical conductivity, thermal conductivity of copper. Which significantly reduces titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, and zinc is little effect, the higher the purity conductivity of pure copper, the better. Sulfur, selenium, tellurium and other solid solubility in copper is very small, and can generate a brittle compound of copper, has little effect on the conductivity, but can reduce the processing of plastic. T1 T2 copper surface color difference between the performance of higher purity copper dark red, rose red T2 conductivity of copper is 98% T1 standard copper conductivity standard formula for the resistance coefficient of 99% copper (1.67 ~ 1.68) × 10-6Ω?

We supply electrical copper has low resistance, bendability advantages. Copper, also known as copper bus bar, copper or copper busbar bus, grounding copper row, copper materials produced by the cross-section is rectangular or chamfered (rounded) rectangle long conductor, produced by the aluminum material called aluminum row, from the transport current in the circuit and connecting electrical equipment role. Since the electrical properties of copper and other than aluminum, copper electrical equipment, power distribution equipment in particular, has been widely applied; generally in the distribution cabinet U, V, W-phase busbars and the PE busbar are made copper; copper in use generally marked with color letter sign or coated with paint, U-phase copper coated with "yellow" color, V-phase copper coated with a "green" color, W-phase copper-coated "Red" color, PE coated copper busbar "green and yellow" color.
