Embodiment Construction

[0015] The cross-linked cable composite insulating sheath outdoor terminal introduced by the present invention, the composite insulating sheath respectively includes the inner wall and the shed made of glass fiber reinforced epoxy resin and silicon rubber from the inside to the outside, the insulating medium uses polyisobutylene, and adopts the The stress cone made of silicone rubber will be described in detail below with reference to the accompanying drawings.

[0016] Fig. 1 is a structural schematic diagram of an outdoor terminal of a cross-linked cable composite insulating sleeve according to the present invention. As shown in Figure 1, the outdoor terminal of the cross-linked cable composite insulating sleeve of the present invention is connected to the end of the cross-linked cable, and the cross-linked cable connected to it includes a cable core 2, a main cable insulation layer 9, an outer semiconducting layer 11 of the cable and a cable metal Set of 18. The outdoor te...

Abstract

The present invention relates to a cable accessory and provides a cross-linked cable composite insulation covering outdoor terminal aiming at the defect of the prior technology that the porcelain insulation covering has low safety. The terminal is connected with the tail end of the cross-linked cable and jacketed on the external side of a cross-linked cable core through a core cavity. The outdoor terminal also includes a composite insulation bushing, an insulation medium and a stress petrous pyramid; the composite insulation bushing is jacketed on the external side of the core cavity, including an internal wall and an umbrella skirt tightly combined from inside to outside and these two are respectively made of glass fiber reinforced epoxide resin and silicon rubber materials; the insulation medium is injected into a hollow cavity between the composite insulation bushing and the external layer of the core cavity; the stress petrous pyramid is arranged on one end of the core cavity and immerges in the insulation medium. When the insulation medium is broken down, the composite insulation composed of a silicon rubber and synthetic resin glass fiber cylinder has strong anti-shocking performance, thus reducing the explosion possibility and further greatly improving the safety of the outdoor terminal.

Description

technical field [0001] The invention relates to cable accessories, and more specifically relates to an outdoor terminal of a cross-linked cable composite insulating sleeve. Background technique [0002] Nowadays, electric energy has become an indispensable source of energy in human life, and the transmission of electric energy from power plants to various power consumers is inseparable from power cables. The safe operation of power cables and their accessories is the basic guarantee for the safe operation of the entire power system. Compared with the cable body, the safety of the cable terminal as one of the accessories is relatively weak. The probability of failure of the transmission line in the past shows that the probability of failure of the cable terminal is quite high. Therefore, as a key connection device, the cable terminal operates The quality of the cable will directly affect the safety of the cable line. [0003] At present, the outdoor terminals of cross-linke...
