This section GB/T 7095 Part 3.

This section identical with IEC 60317-16:1990 "Standard winding wires - Part 16. 155 polyester enamelled copper flat wire" Version 2.0 (English) and amendments No. 1 (1997).

For ease of use, this section made the following editorial changes.

--- Remove the foreword and introduction of international standards;

--- With a decimal point '. 'Instead of a comma as the decimal point,' ';

--- Increased by 3.2 "look and feel";

--- Fixed IEC 60317-16:1990 in the editorial errors, complements Chapter 23, "pinhole test." this section instead of the date of implementation of the GB/T 7095.3-1995.

Section compared with the GB/T 7095.3-1995, major changes in the following.

1 Scope

GB/T 7095 provisions of this part of the polyester resin-based single coat enamelled copper flat wire winding requirements 155. As can be reserved Chemical characteristics of the original resin and meet all the requirements of the provisions of enameled wire, the resin can be modified.

NOTE. chemically-modified resin is a variation of, or contain one or more additives to improve certain properties of the resin or its usage characteristics.

155 represents the thermal level, which requires a minimum temperature index of 155, a heat shock temperature of at least 175 °C.

Corresponding to the temperature index temperature in Celsius is not recommended wire temperature, because it depends on the type of device in use include Many factors within.

This section applies to a conductor nominal size range.

--- Broadside size. minimum 2.00mm, maximum 16.00mm;

--- Narrow size. minimum 0.80mm, maximum 5.60mm.

This section includes Level 1 and Level 2 film thickness enamelled copper flat wire, and is applicable to all specifications conductor.

A combination of size and narrow size broadside and wide/narrow ratio see GB/T 7095.1-2008.
