Qiaopu American power cord

Qiaopu company American plugs voltage 120V, frequency 50/60HZ by the structure is divided into two cores, three cores and polar, nonpolar, to the United States must have a rubber plug brass sleeve; American two-pin plug wire and the zero line of the table distinguish the line of fire: FireWire printing of lines that the other one is the line of fire. Because the American two-pin plug of the two very different films, we can look from the polarity of the plug to distinguish between the zero line of fire line, that is a big zero line plugs feet, small feet for the line of fire.
American power cord structure and properties by wire divided into: NISPT-2 double-insulated flat wire, SPT-1W single insulated wire with a flat groove, SJTW water supply line, SJTO oil supply lines.
NISPT-2: NISPT said double insulation, -2 surface of the two wire line core insulation outer insulation;
XTV and SPT: that single-layer insulation layer, -2 surface of the two-core cable (wire body with a groove, the outer copper conductor insulation package directly);
SPT-3: single-layer insulation with said ground, -3 means three-core cable (wire body with a groove in the middle of the ground of double insulation);
SPT and NISPT are partial lines, SVT is double insulated round wire. Line the outer insulation core insulation
Qiaopu making process in general use in American plugs certification number is not directly hit in the UL logo on the plug.
