How does the fabrication of electronic wires fit with other materials

4 Materials

4. 1 Each material used in AWM shall be compatible with all other materials in the wire and cable. Electronic wire conductor

4.2 Due to possible incompatibility, for example, styrene thermoplastic elastomer materials in flexible wire may be in direct contact with PVC, styrene thermoplastic elastomer materials should not be used. An isolation layer may be used to prevent direct contact. Other potentially incompatible material combinations have not yet been discovered.

4.3 Due to possible incompatibility, uncoated copper, copper alloys, copper coated POTS, copper coated steel, or other elements of exterior masks that are not coated with copper shall not be used in wires or cables that may come into contact with aluminum. Isolation layers may be used to avoid direct contact, or copper members may be coated with metal.

5 conductor

5.1 Overview

5.1.1 A conductor consisting of a single wire is defined as a solid conductor, and a conductor consisting of multiple single wires is defined as a stranded conductor. AWG (United States
National wire gauge), kcmil, and square millimeter each define a nominal cross-sectional area (see Table 5. ○ (regardless of material), hang
The single wire in the combined conductor is not required to conform to a certain American wire gauge or other standard wire gauge size.

The copper core conductor is twisted by multiple strands (each strand consists of one or more flat copper or copper alloy wires helically wound on the polyester wire).

Conductors with tubular cross sections and uniform wall thickness are composed of copper and may be plated with gold.

A confluence bar consists of a single or multiple bars (bars) superimposed into two or more layers. Each bar has a solid rectangular cross section, 2 parallel surfaces, and a rounded edge.

Fibrous wires impregnated or coated with metal (or other conductive materials) may be used as conductors or in combination with other conductor strands.

A carbon fiber conductor is made by twisting multiple carbon fibers, which can be coated with metal.

The resistance line has a set resistance per unit length and is used as the basic heat source of the product.

The electromagnetic wire is composed of a single painted wire, or a combination or stranded of multiple painted wires. Thin film fiber, tape or extruded mix is used as an outsourcing coating to form Ktzwire. The electromagnetic conductor shall have an AWM minimum temperature rating, measured according to UL1446, Insulating Material System.

The dimensions of conductors consisting of or containing conductive fibers, resistance wires (including carbon fiber conductors), tubular conductors, junction bar conductors and electromagnetic wire conductors shall be determined by conductor resistance according to Table 5.6.1. The circular mill area (CMA) of a rectangular conductor is determined by the following formula:

Average width (mils) x Average thickness (mils) X 1.273

AWG dimensions can be determined according to Table 5.1.

5.1.2 It is not prohibited to add fiber to the stranded conductor to be used as a strengthening component to improve the tensile strength. The structure and arrangement of filaments are not specified.

5. 1.3 A composite conductor consisting of a copper conductor and a hard drawn copper alloy wire assembly (as specified in Table 5.3) may be used. The position of the hard drawn copper alloy wire in the finished electronic wire conductor shall not be specified, but shall comply with the following provisions.
a) The cross section of the copper alloy wire shall not exceed 50% of the cross-sectional area of the finished conductor.
b) The minimum conductivity of the finished conductor is 80%IACS standard copper conductor.
c) The maximum temperature of the composite conductor shall be the minimum temperature of the composite material in Table 5.3.

5.2 Metal

5. 2. 1 The service temperature of solid or stranded conductors shall not exceed the temperature specified for the metals in column 3 of Table 5. 3. Conductor metal correspondence
In accordance with ASTM, as shown in Table 5. 3.

5.3 Dimensions and cross-sectional area

5.3.1 The size of the round solid conductor shall not be smaller than the values shown in Table 5.1 or Table 5.2. Measurement methods refer to UL1581, Section 200,

"Conductor diameter". The size of the round solid conductor cannot be greater than the nominal value of the adjacent larger conductor size in Table 5.1.

The actual width and thickness of the conductor of the solid round wire in Exception 6 of Exception 41.2(d) shall be located in the label,
Within the range of -1% and +10% of the marked diameter of wire reel and carton.

5. 3. 2 The size of rectangular solid conductor cannot be smaller than the value shown in Table 5. 1. Refer to Table 5.1 for measurement methods.

Exception: The actual dimensions of the conductor of solid rectangular wire in Exception 7 of 51.2(d) shall be located in the label, wire
Within the range of -1% and +10% of the marked width and thickness of plates and cartons.

5. 3. 3 The cross-sectional area of the stranded or braided conductor shall not be less than the corresponding values shown in Table 5.1 or Table 5.2. May be determined by any of the following
.

a) The sum of the areas of its circular or rectangular strand members;

b) Weighing method in UL1581. Suitable for round tightly compressed aluminum conductor or compressed stranded copper conductor or aluminum conductor.
The cross-sectional area of the stranded conductor cannot be greater than the nominal size of the adjacent larger conductor in Table 5.1.

5. 3. 4 conductor consists of unallored copper with a conductivity of not less than 97%IACS in section 51.2 (f) "Exception", 5. 6. 1 to
The method of determining conductor resistance in section 5. 6. 3 May be used as an alternative to measuring conductor dimensions and, if in dispute, as a determination
Reference method for conductor size.

5.3.5 The conductor shall consist of non-alloy copper with a conductivity of not less than 97%IACS in Section 51.2 (f) "Exception", may
Use the method for determining conductor resistance in sections 5. 6.1 through 5. 6.3.

5. 3.6 For copper conductors, use UL1581, Section 22, "DC Conductor Resistance "for determination of conductor resistance on labels.

5.4 Metal Coating

5. 4. 1 As determined in UL1581 Section 500 conductor corrosion test, with copper, copper alloy, or copper clad aluminum, copper clad steel conductor

The proximity of the fiber wire or insulation layer will corrode unprotected copper wire, and no protective insulation layer is provided, in solid conductor or stranded wire
Each conductor shall be coated with section 4. 1 metal or alloy (if applicable in finished wire).

5.4.2 If the stranded conductor does not require anti-corrosion protection but only to prevent the insulation from bonding to copper, only the outer conductor may be coated.
