Embodiment 1

[0024] see figure 1 and figure 2 , the 110KV and above prefabricated dry-type cable terminal accessories of the present invention are used to connect the cable 10 to electrical equipment (not shown in the figure), including at least one crimping liner 20, terminal 30, sealing tube 40, and terminal insulator 50 and stress control body 60.

[0025] The cable 10 includes a cable conductor 11 , an optical fiber sheath 12 disposed in the cable conductor 11 , at least one optical fiber 13 sheathed in the optical fiber sheath 12 , and a cladding layer 14 outside the cable conductor 11 .

[0026] The crimped liner 20 may consist of one segment or several segments.

[0027] Preferably, the crimping liner 20 is made of a hard metal crimping liner, or a hard polymer material.

[0028] In this embodiment, the crimping liner 20 is disposed in the optical fiber sheath 12 of the cable 10 and sleeved outside the optical fiber 13 , and the crimping liner 20 is directly sleeved outside the ...

Embodiment 2

[0035] see image 3 , image 3 is the enlarged schematic diagram of I', where the position of I' is the same as figure 1 The position at I is the same, which discloses an embodiment in which the crimping liner is arranged inside the cable conductor and outside the fiber sheath. This embodiment is similar to Example 1, the difference being that the crimping liner 20' is set on The cable conductor 11 of the cable 10 is located outside the optical fiber sheath 12 , and the crimping liner 20 ′ is indirectly located outside the optical fiber 13 . The optical fiber 13 of the cable 10 is led out from one end of the optical fiber sheath 12 .

[0036] The 110KV and above prefabricated dry-type cable terminal accessories of the present invention are provided with a crimping liner 20' outside the optical fiber sheath 12 of the cable conductor 11. When the cable conductor 11 is crimped and connected, the crimping liner 20' bears the crimping force, which prevents the optical fiber 13 i...

Embodiment 3

[0038] see Figure 4 , Figure 4 It is the enlarged schematic diagram of I'', where the position of I'' is the same as figure 1 The position of I is the same, which discloses Embodiment 3 of the 110KV and above prefabricated dry-type cable terminal accessories of the present invention. This embodiment is similar to Embodiment 1, and the difference is that: the cable conductor 11 of the cable 10 is located in the optical fiber A crimping liner 20 ″ is further provided outside the sheath 12 , and the crimping liner 20 ″ is indirectly located outside the optical fiber 13 .

[0039] The 110KV and above prefabricated dry-type cable terminal accessories of the present invention are provided with a crimping liner 20 inside the optical fiber sheath 12 of the cable conductor 11, and a crimping liner 20'' outside the optical fiber sheath 12, and between the crimping tube 31 and the cable When the conductor 11 is crimped and connected, the crimping liner 20 / 20'' bears the crimping forc...

Abstract

The invention discloses a 110KV and above prefabricated dry-type cable terminal accessory, which is used for connecting a cable onto an electrical device. The 110KV and above prefabricated dry-type cable terminal accessory comprises a connecting terminal, a sealing pipe, a terminal insulation body, a stress control body and a crimping liner pipe. The cable comprises a cable conductor, an optical fiber jacket and optical fibers. The connecting terminal is connected with the cable conductor. The terminal insulation body is preset on the cable, and the stress control body is arranged in the terminal insulation body. The sealing pipe is sleeved on the top ends of the connecting terminal and the terminal insulation body. The crimping liner pipe is arranged in the cable conductor and arranged inside and / or outside the optical fiber jacket. The optical fibers are led out from the free end of each of the crimping liner pipe, the optical fiber jacket and the cable conductor and an optical fiber lead-out port of the connecting terminal and are connected with the optical fibers which are preset inside the terminal insulation body. The crimping liner pipe is arranged inside and / or outside the optical fiber jacket of the cable conductor, when the connecting terminal is connected with the cable conductor, the crimping liner pipe bears the crimping force, so that the optical fibers can be prevented from being damaged by the squeezing force, and the damage-free connection of the optical fibers in the cable can be realized.

Description

technical field [0001] The invention relates to a cable terminal accessory, in particular to a 110KV and above prefabricated dry-type cable terminal accessory. Background technique [0002] In order to solve the overheating problem of 110KV and above cable conductors in traditional cables, an optical fiber is installed outside the cable to measure the temperature of the cable conductors, so as to avoid fire accidents caused by overheating of the cable conductors. [0003] However, the above-mentioned optical fiber is arranged outside and in the middle of the cable with an insulating layer, which makes the measurement inaccurate. In order to measure the heating temperature of the cable conductor more accurately, people adopt the method of directly placing the optical fiber in the cable conductor. However, how to connect the cable with the optical fiber embedded in the cable conductor to the electrical equipment has become an urgent problem in the industry. Contents of the i...
