The alloy arch layer, the heat-resistant aluminum alloy arch layer is provided with a steel core, the steel core and the heat-resistant aluminum alloy arch layer are provided with a gap, and the heat-resistant silicon 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...
