Relevant specifications for the use of plug wires and their wiring

Plug and cable types around the world

The differences and applications of four commonly used plug wires

1、 European plug cable

① European plug: also known as Dutch standard power plug or pipe plug

The plug cable has dealer and dealer model specifications such as AW-006 JJ-002, and has been verified by countries around the world: (D (Netherlands); N (Denmark); S (Germany); VDE (France); FI (Germany); IMQ (Spain); KEMA (Spain); CEBEC (Denmark).

Pin suffix: N/1225

② Wiring signs indicate with code: H05VV □ □ F 3G 0.75mm2:

H: Indicating European regulations and EU country logos

05: Indicates the compressive strength of the wiring (03:300V 05:500V)

VV: the insulation layer of the wire core on the surface of the front V, and the insulation layer of the protective wire sleeve on the rear V indicate the wiring. For example, if RR indicates the insulation layer of vulcanized rubber, if VV: N indicates the insulation layer of chloroprene rubber;

□ □: The unique code in the front "□" indicates a flat wire, or H2 indicates a flat two core wire;

F: Indicates that the line is a circular line

3: Indicates the number of internal cores

G: Indicate grounding device

0.75 mm2: indicates the cross-sectional area of the wiring

Indication of European standard line markings

2、 British standard plug cable

① Insert in English: 240V 50HZ, 3750V, 3S, 0.5mA, safety tube (2A 10A, 13A) (FVSE) → safety tube, specifications: total length 25-26.3mm, middle diameter 4.7-6.2mm, metal material cap diameter on both sides 6.25-6.5mm (screen printing ink BS1362);

② The internal wire of its plug wire (when disassembling the BS power plug, it is facing the right side of itself to connect the L-wire (fire) to the safety tube, and the length of the grounding wire must exceed three times the length of the (fire line zero line, zero line). Loosen the fixed screw and use external force to pull it out to remove the wire. The fixed screw that fixes the three fixed wires must be conical.).

③ Identification is the same as European plug wires.

3、 American plug cable

① American plug wires: 120V 50/60HZ are divided into two core wires, three core wires, and optical rotation and non polarity. The metal sheets of plug wires to the United States must have plastic sleeves;

The root line of the two core wire hot stamping indicates the zero line of the hot wire; The large pin of the optical power plug is the zero wire, and the small pin is the live wire zero wire (the convex and concave surface of the power wire is zero, and the round surface of the wire is the live wire zero wire);

② American power cord types: NISPT-2 two-layer insulated flat wire, SPT-1W single-sided insulated flat wire with concave groove, SJTW moisture-proof power cord, SJTO oil-resistant power cord, etc

American power cord power plug

NISPT-2: NISPT indicates two layers of insulation, with -2 surface layers of two core wire core insulation and surface layers of insulation;

XTV and SPT: indicate a single-sided insulation layer, with a -2 surface layer of two core wires (the entire wire has a concave groove, and the surface insulation is immediately wrapped with a copper core electrical conductor);

SPT-3: indicates a single sided insulated grounding wire, -3 indicates a three core wire (with a concave groove in the entire wire, and the middle is the grounding wire with two layers of insulation);

SPT and NISPT are both offset wires, while SVT has two layers of insulation for circular wires. Core insulation surface insulation

③ The verification serial number of American plugs is generally not immediately marked with UL pattern design on the top of the plug. For example: E233157 E236618

④ American plug cables are different from European plug cables:

European plug wires are indicated by "H";

The number of lines used in the US regulations is indicated as follows: 2 × 1.31mm2（16AWG）、2 × 0.824mm2 (18AWG): VW-1 (or HPN) 60 ℃ (or 105 ℃) 300V

2: Indicate the total number of wire cores;

1.31 or 0.824 mm2: indicates the cross-sectional area of the wire core;

16AWG: indicates the cross-sectional area of the wire core, and mm2 is relative to the above;

VW-1 or HPN: VW-1 is PVC material; HPN: Neoprene material

60 ℃ or 150 ℃ is the high temperature resistance level of the power cord;

300V: The compressive strength of the power cord is different from that of the European standard (indicated by 03 or 05 in the European standard).

4、 Japanese plug cable: PSE, JET

VFF 2*0.75mm2 -F-

① VFF: V indicates that the wire material is PVC; FF is a single sided insulation layer with concave grooves for the entire line;

② VCTFK: PVC surface wire material; TFK is a two-layer insulation layer flat wire, with a surface insulation layer, an inner insulation layer, and a copper core transmission line;

③ VCTF: VC indicates that the wire material is PVC; TF is a two-layer insulated circular wire;

④ There are two types of wiring: one is 3 × 0.75mm2, another type is 2 × 0.75mm2

three × 0.75mm2:3 indicates a three core wire; 0.75mm2 indicates the cross-sectional area of the wire core;

⑤ F: indicates the material of the flexible cable;

⑥ The Japanese triple plug plug has two springs, and the grounding wire is immediately locked onto the power socket (with good safety and convenience).
