GB/T 23310-2009Aromatic polyimide tape wrapped rectangular copper wire, class 240 (English PDF)

Foreword

This standard is equivalent to IEC 60317-44.:1997 "Special Winding Wire Product Standard Part 44. Class 240 Aromatic Polyimide Film Wrapped copper flat wire "first edition (English version).

For ease of use, this standard has been modified as follows.

- the preamble and introduction to IEC 60317-44.:1997 were deleted;

--- replace the comma as a decimal point with a decimal point. "

--- an increase of 3.3 "appearance" and Chapter 23 "pinhole";

- Added in Chapter 15 the use of flat wire samples for temperature index test requirements.

This standard is equivalent to the use of IEC 60317-44.:1997 amended the original editorial error as follows.

- change the "softening breakdown" in Chapter 10 from "not applicable" to "test requirements are under consideration";

- change the "hot bonding or solvent adhesion" in Chapter 18 to "hot bonding".

1 Scope

This standard specifies the requirements of the 240 grade aromatic polyimide film wrapped copper flat wire, which is insulated by one or two layers of polyimide film with composition.

The 240 grade indicates the heat level, which requires a minimum temperature index of 240 and a thermal shock temperature of at least 260 ° C.

Note. Some countries, such as Canada, Russia and the United States, are 220.

Film with a single or double-sided coated with a suitable binder, such as perfluoroethylene propylene. After the film is wrapped, it can form continuous and bond by sintering of the jacket.

Special requirements may be specified in the contract.

The Celsius temperature corresponding to the temperature index is not the recommended winding line temperature, as this depends on the type of equipment used Many factors within.

The nominal size of the conductors to which this standard applies is.

--- width. minimum 2.00mm, maximum 16.00mm;

--- Thickness. minimum 0.80mm, maximum 5.60mm.

The combination of width and thickness and the width/thickness ratio are specified in GB/T 7095.1-2008.

When referring to the products covered by this standard, the following should be given.

--- GB number and/or IEC number;

--- Nominal size of conductor (width × thickness);

---level.

Example. GB/T 23310-2009 1.00mm × 4.00mm A2 grade or IEC 60317-44 4.00mm × 1.00mm gradeA2
