Title:
ANTI-SEISMIC FIRE-RESISTANT POWER CABLE
Document Type and Number:
WIPO Patent Application WO/2024/027036
Kind Code:
A1
Abstract:
Provided is an anti-seismic fire-resistant power cable, comprising an anti-seismic frame (3) and low smoke zero halogen polyolefin sheaths (4). The low smoke zero halogen polyolefin sheaths (4) are equidistantly arranged inside the anti-seismic frame (3), and mineral fire insulation layers (401) are fixedly arranged at the backs of the low smoke zero halogen polyolefin sheaths (4). By equidistantly arranging the low smoke zero halogen polyolefin sheaths (4) inside the anti-seismic frame (3), the fireproof capability of the power cable can be improved by using the low smoke zero halogen polyolefin sheaths (4) and the mineral fire insulation layers (401), thereby solving the problems that an existing power cable has poor flame-retardant and fire-resistant effects and is easy to cause secondary pollution and disasters; the structural strength of the power cable is improved by using aluminum sleeve isolation layers (403) and central reinforcing members (406); a support frame (302) and a rubber frame (301) are used to realize multi-stage protection on the power cable, thereby improving the anti-seismic effect of the power cable; a hanger is mounted by using mounting bolts (101), and the anti-seismic effect of the power cable is further improved by using reinforcing rods (203).
