Medium-voltage soft-conductor photoelectric integrated cable

Abstract

The invention discloses a medium-voltage soft-conductor photoelectric integrated cable comprising a plurality of power units. The power units are covered with a water stop layer, a liner layer, a wire armored layer and an outer sheath layer in order. A plurality of fiber units are disposed in gaps among the power units. Each power unit comprises a soft-conductor wire core which is covered with an inner shield layer, an insulating layer and an outer shield layer in order. Each fiber unit comprises a loose tube accommodating a fiber core, fiber paste and a reinforcing wire, and the loose tube of the fiber unit is covered with an asbestos cloth layer and a silicone layer in order. When the medium-voltage soft-conductor photoelectric integrated cable operates at high temperature for a long time, the interior temperature of the cable can be lower than 60 DEG C, and the transmission performance of the cable is unaffected; in addition, the asbestos cloth and silicone wrapping the fiber units also has the function of enhancing fiber outer support, and the fiber units are protected from crush when the fiber units and the power units are stranded into the cable.

Description

technical field [0001] The invention relates to a medium-voltage flexible conductor photoelectric integrated cable. Background technique [0002] The photoelectric composite cable is a composite cable that integrates optical fiber and power transmission cable, which can realize optical fiber communication and transmit power at the same time, and can avoid the problem of secondary wiring during construction. Optical cables and power cables have different requirements on the working environment. For example, the more important working environment indicators are ambient temperature and ambient humidity. The ambient temperature of optical cables is generally around 60°C, while the normal operating temperature of power cables is between 40°C and 90°C. During the period, optical cables have strict restrictions on humidity, so optical cables and power cables cannot be simply superimposed and combined for use.
