Wire and cable fire resistance test device

‍ The device meets the requirements of GB/T18380.1-2001 and IEC60320-1-2, and is suitable for vertical burning test of single wire and cable products to determine the combustion characteristics of the insulating materials. The flame height can be easily adjusted according to the preset burn time of the sample.

1. The wire and cable fire resistance test machine is designed and manufactured according to the requirements of GB/T18380.1 and GB/T18380.2, and is used to test the fireproof condition of a single wire or cable during vertical burning test.

1. The test method specified in the GB/T18380.1 standard is not applicable to small-sized strands with a conductor diameter of less than 0.8 mm or small-sized strands with a cross-sectional area of ​​less than 0.5 mm2 because the conductors are melted before the end of the test.

2. The test method specified in GB/T18380.2 is that the test method specified in GB/T18380.1 is not applicable. If some small-size conductors may be melted during the fire, the GB/T18380.2 standard may be used. Method The insulated wire was subjected to a burning test under flame conditions. The recommended range is for solid copper conductors with a diameter of 0.4 to 0.8 mm and a stranded copper conductor with a cross-sectional area of ​​0.1 to 0.5 mm2.
