Special-shaped copper belt
Special-shaped copper belt is an indispensable conductive material for high-low electrical switches and power supply installation. Special-shaped copper belt technical parameter. copper content≥99.90%. Production by customers technique. Quality can meet customers need. |
| Trapezoidal Copper bar is necessary material for producing DC motor, exciter motor, commutator of motor enlarger, special electric switch and coil ring. TH11PT(Trapezoidal copper-silver alloyed bar Class1): Ag content(%): 0.08-0.15; 0.16-0.25 TH12PT(Trapezoidal copper-silver alloyed bar Class2) TPT pure trazepoidal copper : technical parameter TPT Surface hardness should be ranked 80-105 HB, TH11PT/TH12PT Surface hardness should be ranked 85-105 HB. Angle of trapezoidal copper bar can be made according to model; gap of two side plate, is not more than ruled dimension of clearance gauge. Height(mm) | Clearance gauge(mm) | H≤30.00 | 0.03×3 | 30.00H≤80.00 | 0.05×7 | 80.00H≤100.00 | 0.08×10 | 100.00H≤150.00 | 0.10×10 |
