The embodiment of the invention discloses strain clamp, to satisfy higher ampacity requirement.
Strain clamp of the present invention comprises that an end has the drainage plate of one or more grooves, and an end is connected and shape and the suitable drainage tube of described groove with the end that described drainage plate has groove.
Fig. 1 shows a kind of structure of strain clamp, comprises strain clamp body 1, steel anchor 2 (part that dotted line encloses among Fig. 1), drainage plate 3 and drainage tube 4.
Wherein:
Drainage plate 3 (side-looking) end is a hollow tubular, welds together with strain clamp body 1 to be used to being inserted in strain clamp body 1 back, and the other end of drainage plate 3 then has a groove 8.
One end, 9 shapes of drainage plate 4 (side-looking) and the groove of drainage plate 38 are suitable and can insert in the groove 8, and its other end is one section hollow tube 10, and this hollow tube is used to be inserted in wire jumper.For satisfying different needs, the center line 901 of drainage plate one end 9 can overlap with the axial line 101 of hollow tube 10 or angled as 30 ° (referring to Fig. 2), and those skilled in the art can select according to actual conditions.
In actual applications, overhead transmission line mostly is steel reinforced aluminium conductor, and wherein, most pulling force that overhead transmission line is subjected to are born by steel core, and aluminium stranded conductor then is mainly used in transmission current.Fig. 3 has provided the combination section of strain clamp: during construction, the steel core 12 of overhead transmission line 11 is passed strain clamp body 1, and steel core 12 is inserted in the hollow tube 7 of steel anchor 2 (part that dotted line encloses among Fig. 3).Subsequently, hollow tube 7 pressurizations to steel anchor 2 make it to be crimped on steel core 12.Subsequently, the hollow tube 7 of steel anchor 2 is inserted in the strain clamp bodies 1 together with solid section 6, to strain clamp body 1 and solid section 6 contacted positions pressurizations, make steel anchor 2 and strain clamp body 1 can form clamping and combine again.In addition, tube wall 13 pressurizations that also will contact with strain clamp body 1 overhead transmission line 11, thus realize combining of overhead transmission line 11 and strain clamp body 1.
Being connected between drainage plate 3 and the drainage tube 4 then be to insert in the groove of drainage plate 3 by the end (shape of the groove of this end shape and drainage plate 3 is suitable) with drainage tube 4, and use one or more bolts 14 that drainage plate 3 and drainage tube 4 are locked together and realize.The other end that drainage tube 4 is hollow tubular then is inserted in wire jumper 15.
