Title:
FIRE-RESISTANT POWER CABLE FOR FULL-LINE TEMPERATURE MEASUREMENT AND ALARM SOUNDING
Document Type and Number:
WIPO Patent Application WO/2020/119443
Kind Code:
A1
Abstract:
A fire-resistant power cable for a full-line temperature measurement and alarm sounding, comprising a fire-resistant line core and a sheath layer (11) at an outer part thereof, wherein first and second spaces are formed between the fire-resistant line core and the sheath layer (11); a first monitoring line and a second monitoring line are disposed in the first space and the second space respectively, the first monitoring line comprises two first steel wires (4), and first heat-sensitive insulating materials (5) wrap the outside of the first steel wires (4); the second monitoring line comprises two second steel wires (7), and second heat-sensitive insulating materials (8) wrap the outside of the second steel wires (7); in the first space, the first monitoring line is in contact with the fire-resistant line core, and there is a first thermal insulation filler (6) between the first monitoring line and the sheath layer (11); and in the second space, the second monitoring line is in contact with the sheath layer (11), and the second monitoring line and the fire-resistant line core are separated by means of a second thermal insulation filler (9). The fire-resistant power cable above may monitor the ambient temperature of the entire laid line and the temperature of the cable surface, and sound an alarm when the temperature is exceeded.
