Commonly used plugs with four power cords
1、 European plug
① European plug: also known as French standard plug or pipe plug
The plug has suppliers and supplier specifications such as KE-006 YX-002, as well as certifications from various countries: (D (Denmark); N (Norway); S (Sweden); VDE (Germany); FI (Finland); IMQ (Italy); KEMA (Netherlands); CEBEC (Belgium).
Pin suffix: N/1225
② Power cord identification with code: H05VV □ □ F 3G 0.75mm2:
H: Mm2 identification
05: Indicates the withstand voltage strength of the power cord (03:300V 05:500V)
VV: The insulation layer of the surface core of the front V, the insulation layer of the sheath of the power line, represented by RR as the rubber insulation layer, represented by N as the chloroprene rubber;
□ □: The first "□" is marked with a special code, and the last "□" represents a flat wire. For example, adding H2 represents a flat two core wire;
F: Indicates that the line is a soft wire
3: Indicates the number of internal cores
G: Indicates grounding
0.75mA: represents the cross-sectional area of the power cord
③ PVC: Material refers to the material used to strengthen the insulation layer, which can withstand high temperatures below 80 ℃. Soft PVC also has a hardness of 78 ° 55 °. The larger the number, the harder the temperature resistance, and the higher the temperature resistance. Rubber wire can withstand temperatures up to 200 ℃ or below. The same hardness (PVC) soft wire is used.
2、 English insertion
① British plug: 240V 50HZ withstand voltage 3750V 3S 0.5mA, fuse (3A 5A 10A 13A) (FUSE) → fuse, size requirements: total length 25-26.2mm, middle diameter 4.7-6.3mm, metal cap diameter at both ends 6.25-6.5mm (silk screen BS1362);
② The internal wires of its plug (open the BS plug and connect it to the fuse on the right side of the L-wire (fire). The length of the ground wire must be greater than three times the length of the (fire wire, zero wire). Loosen the fixing screw and use external force to pull out the wire. The ground wire must finally fall off (the fixing screw for fixing the three wires must be conical).
③ The identification of the power cord is the same as that of the European plug.
3、 American plug
① American plug: 120V 50/60HZ is divided into two core wires, three core wires, and polarity and non polarity. The copper strip of the power plug to the United States must have a plug terminal sheath;
The line printed on the two core wire represents the hot wire; The connection wire with a large polarity plug pin is a zero wire, while the connection wire with a small pin is a live wire (the concave and convex surface of the power cord is zero, and the circular surface of the line is a live wire);
② There are two modes of wire: NISPT-2 double-layer insulation, XTV, and SPT single-layer insulation
NISPT-2: NISPT represents double layer insulation, with -2 surface two core wires insulated and outer layer insulated;
XTV and SPT: Refers to a single layer of insulation layer, with -2 surface two core wires (with grooves in the wire body and copper core conductors directly wrapped in the outer insulation);
SPT-3: represents a single layer insulated ground wire, -3 represents a three core wire (with a groove in the wire body and a double layer insulated ground wire in the middle);
