GB/T 13542-1992Film for electrical insulation -- Part 1: Definitions and general requirements (English PDF)

Foreword

GB/T 13542 "Film for electrical insulation" is divided into the following sections.

--- Part 1. Definitions and general requirements;

--- Part 2. Test methods;

--- Part 3. biaxially oriented polypropylene film capacitors;

--- Part 4. Polyester film;

This section GB/T 13542 Part 1.

The partial modification using IEC 60674-1. 1980 "plastic films for electrical purposes - Part 1. Definitions and general requirements" (in English).

This part of IEC 60674-1 and the main technical differences are as follows.

1) A "Normative References" chapter;

2) A "inspection rules" chapter.

This Part replaces GB/T 13542-1992 "General requirements for plastic films for electrical purposes." the main difference compared to part with the GB/T 13542-1992 as follows.

1) The "standard reference" to "normative references";

2) the definition of 3.1.1 "skew" to "Offset/arc." this part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized.

3 Terms and Definitions

The following terms and definitions apply to this section.

Evaluation of the film wound into a roll for the film deformation, can be offset/arc and two depressions measure.

3.1.1

When the film opened flat, its edge is not a straight line (offset or curved).

3.1.2

When the period of the film consists of two parallel horizontal position of the roller support and withstand a certain tension of the situation, some of which would be lower than the total film the horizontal plane.

Since the film roll wound does not close, the film roll part for axial movement called off the rest of the cylinder occurs.
