A low-voltage soft power cable for naval ships

Abstract

A low-voltage soft power cable for naval ships including jackets, the protective sleeve is sleeved on the outer wall of the sealing sleeve gasket, the sealing sleeve gasket is mounted on the outer wall of the protective layer, the copper core stranded conductor is arranged inside the protective layer, An insulating layer is sleeved on the outer wall of the copper core stranded conductor, a connector is installed at the front end of the sheath, a groove is arranged at the front end middle part of the connector, the tail end of the groove is abutted with the front end of the conductive block, anexpansion spring is installed at the center of the inner bottom surface of the conductive block, and an abutment plate is installed at the front end of the expansion spring. By arranging the sheath,The filling layer, anti-slip grain, sealing sleeve, protective layer, connecting piece and sealing ring, the problems of short service life, poor compression resistance, extrusion damage to stranded conductor of copper core, unstable grip of water on cable surface, slip off of hand, inconvenient connection of cable and unsafe use of connecting piece are solved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a low-voltage flexible power cable for ships. Background technique [0002] Low-voltage cables are usually rope-like cables twisted by several wires or groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating coating. Cables refer to materials used for power, communication and related transmission purposes. There is no strict boundary between wires and cables. Products with fewer cores, small diameters, and simple structures are usually called wires, and those without insulation are called bare wires. Others are called cables; those with a larger conductor cross-sectional area, greater than 6 square millimeters, are called large wires, smaller ones, less than or equal to 6 square millimeters, are called small wires, and insulated wires are also called cloth wires. Wires a...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a low-voltage flexible power cable for ships, which solves the problem of short service life of the cable and poor compression resistance, and the damage of the copper core stranded conductor by external force extrusion affects the normal use of the cable. In the presence of water, the grip is not firm, the hand slips and falls off, the cable connection is inconvenient and the use of the connector is unsafe.
