Abstract

The invention relates to the field of cables, in particular to a fire-resistant optical fiber composite bunched cable and a preparation method thereof. The fire-resistant optical fiber composite bunched cable comprises four cables and an optical fiber, wherein a connecting rib is arranged between the cables; a connecting rib is arranged between one of the cables and the optical fiber; connecting rib holes are formed in the connecting rib; the cable comprises an insulating layer; a mica tape is arranged in the insulating layer; a heat-resistant aluminum alloy round wire layer is arranged in themica tape; a heat-resistant aluminum alloy arched layer is arranged in the heat-resistant aluminum alloy round wire layer; a steel core is arranged in the heat-resistant aluminum alloy arched layer;a gap is formed between the steel core and the heat-resistant aluminum alloy arched layer; and heat-resistant silicon lubricating grease is filled in the gap.

Description

technical field [0001] The invention relates to the field of cables, in particular to a fire-resistant optical fiber composite bundled cable and a preparation method thereof. Background technique [0002] Power fiber-to-the-home can not only meet the needs of the smart grid's own development, but also fully support the integration of the three networks. Power fiber-to-the-home can realize the co-construction and sharing of network infrastructure, greatly reduce the implementation cost of "triple play", improve the comprehensive operation efficiency of the network, and have obvious advantages in energy saving and environmental protection. Power optical fiber to the home technically realizes only one construction, one channel, and one-time solution to the problem of photoelectric composite cable entering the home. It can replace the multiple constructions of multiple lines such as electric wires, network cables, telephone lines, and cable TV. Save cable resources and public s...
