Embodiment Construction

[0014] Depend on figure 1 It can be seen that the present invention consists of a flame-retardant sheath, an inorganic glass fiber filler and a wire core. The inorganic glass fiber filler is located between the flame-retardant sheath and the wire core. The wire core is composed of a fire-resistant insulating layer and a copper conductor therein.

[0015] There are 5 wire cores, the wire cores cut inwardly with the inner wall of the flame-retardant sheath, and the two adjacent wire cores cut outwardly.

[0016] The flame retardant sheath is made of polyolefin.

[0017] The copper conductor is made of oxygen-free copper.

Abstract

The invention relates to cables, in particular to a flame-retardant, flexible, fireproof and environment-friendly low-voltage power cable. The cable comprises a flame-retardant protective sleeve, inorganic glass fiber filler and a cable core. The inorganic glass fiber filler is located between the flame-retardant protective sleeve and the cable core. The cable core comprise a fireproof insulating layer and a copper conductor in the fireproof insulating layer. Compared with the conventional cables, the cable is resistant to high temperature, low temperature and aging and good in insulating performance.

Description

Technical field: [0001] The invention relates to a cable, more specifically, to a flame-retardant, flexible, fire-proof and environment-friendly low-voltage power cable. Background technique: [0002] Traditional power cables include flame-retardant plastic insulated and sheathed power cables with a rated voltage of 0.6 / 1KV and below, 0.6 / 1KV XLPE insulated power cables, copper core plastic insulated fire-resistant power cables with a rated voltage of 0.6 / 1KV and below. The above products are suitable for power transmission in 0.6 / 1KV and below power lines. [0003] The above-mentioned cables have the following disadvantages: the conductor of the product is made of oxygen-free copper. When the cable is in normal use, the long-term allowable working temperature of the conductor does not exceed 90°C. And smog generation, poor environmental protection performance, not suitable for important occasions with high safety requirements and dense personnel. Invention content: [0...
