Scope

GB/T 16935 provisions of this part of the low-voltage system equipment insulation coordination, this section applies to altitude to.2000m, rated power
Pressure to 1000V, rated frequency to 30kHz or DC to 1500V equipment.
According to the equipment performance standards, this part of the provisions of the equipment clearances, creepage distances and solid insulation requirements. This part of the package
Including the insulation with the electrical test methods.
The minimum electrical clearance specified in this section does not apply to have ionized gas Department. Special requirements for this situation can be met by the corresponding product
Standard Technical Committee to deal with their own products.
This section does not involve determining the following distances.
--- through the liquid insulation;
--- Pass gas other than air;
--- By compressed air.
Note 1. Insulation coordination of equipment within the low-voltage system of rated frequency above 30kHz according to IEC 60664-4.
Note 2. The internal circuitry of the device may exhibit higher voltages.
Note 3. The guidelines for determining the size above.2000m above sea level are shown in Table A. 2.
This section is the basic electrical safety standards, designed to guide the technical committee responsible for product standards for its various equipment responsible for the development of
The requirements, to achieve the purpose of insulation.
This section for each product standard technical committee to determine the equipment in the air gap, creepage distance and solid insulation provided the necessary
Guidance information.
Manufacturers and product standards Technical Committee has the responsibility to apply the requirements of the basic safety standards, if necessary, standard equipment
Cite these requirements.
If the relevant product standard does not specify the values of clearances, creepage distances and the requirements for solid insulation, or in the absence of standards
Under this section applies.

Summary	This standard specifies the low-pressure system equipment insulation coordination, this section applies to altitude to 2000m, AC rated voltage to 1000V, rated frequency to 30kHz or DC to 1500V devices. Depending on the device performance standards, this section of the equipment clearances, creepage distances and solid insulation requirements were specified. This section includes information about Electrical test methods for insulation coordination. This section provides the minimum clearances apply to the Department with ionized gas. For this case the special requirements from the corresponding product standards technical committee itself. This section does not involve determining the following distance: through the liquid insulation, through a gas other than air, compressed air. This section is based on electrical safety standards, product standards designed to guide the technical committee responsible for a variety of equipment for its reasonably formulate relevant requirements, to achieve insulation coordination purposes. This section of the Product Standards Technical Committee to determine the device in the air clearances, creepage distances and solid insulation provides the necessary guidance information. Manufacturers and product standards technical committee has the responsibility of applying the basic safety standard requirements, if necessary, in the range of equipment standards referenced in these requirements. If the relevant product standard does not require clearances, creepage distances and the value of solid insulation requirements, or, in the case of the standard, this section applies.
