Cable fire blanket passes a high-voltage arc simulation
The sample stayed intact with no perforation and no ejected debris, and showed self-extinguishing behaviour after the arc.
The cable fire and explosion blanket grew out of the cable fire blanket, which was originally made to a European customer's specification. As the domestic power industry began to adopt fire blankets for cable runs, our team adapted the design to local conditions. At that stage there was no dedicated national standard for this product and field practice was still being worked out.
As operating experience accumulated, customers added requirements, and blast protection became one of them. The present blanket is expected to meet physical, mechanical, electrical, explosion and combustion criteria at once. In the arc simulation the sample remained intact, without perforation or internal debris ejection, and showed self-extinguishing behaviour. The test was run by the Suzhou Electrical Apparatus Science Academy; the report number is given on the customer copy.
