Embodiment 1
[0030] see figure 1 and figure 2 , 110KV and above cable terminal accessories of the present invention relate to oil-filled cable terminal accessories, which are used to connect cables 10 to electrical equipment (not shown in the figure), including at least one crimping liner 20, a connecting piece 30, and a stress control body 40. Insulating sleeve 50, two mounting flanges 60, shielding cover 70 and outlet fittings 80.
[0031] The cable 10 includes a cable conductor 11 , an optical fiber sheath 12 disposed in the cable conductor 11 , and at least one optical fiber 13 sheathed in the optical fiber sheath 12 .
[0032] The crimped liner 20 may consist of one segment or several segments.
[0033] Preferably, the crimping liner 20 is made of a hard metal crimping liner, or a hard polymer material.
[0034] One end of the wiring member 30 is provided with a wiring hole 31 and an optical fiber outlet hole 32 , and the optical fiber outlet hole 32 communicates with the wiring h...
Embodiment 2
[0043] 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' is located outside the optical fiber jacket 12', and the crimp 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'.
[0044] The 110KV and above cable terminal accessories of the present invention are equipped with a crimping liner 20' outside the optical fiber sheath 12' of the cable conductor 11', and the optical fiber 13' of the cable 10' comes out from one end of the optical fiber sheath 12' and is drawn out through the optical fiber outlet hole 32. , the length of the stra...
Embodiment 3
[0046] 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 at I is the same, which discloses Embodiment 3 of the 110KV and above cable terminal accessories of the present invention. This embodiment is similar to Embodiment 1, and the difference is that: the cable conductor 11'' is located outside the optical fiber sheath 12 and further A crimping liner 20 ″ is provided, and the crimping liner 20 ″ is indirectly located outside the optical fiber 13 .
[0047] The 110KV and above 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'' is set outside the optical fiber sheath 12, and between the connector 30 and the cable conductor 11 When crimping the connection, the crimping liner 20 / 20'' bears the crimping force, which prevents the optical fiber 13 in the crimping liner 20 / ...
