The utility model discloses a puncture ground wire clamp that is firm, relates to installation equipment technical field, this puncture ground wire clamp that is firm, including puncture clamp and the sleeve shell of setting in the outside of puncture clamp, the utility model discloses the setting of
protection mechanism, when the device is to use, the sleeve shell and the lower sheath that can protect inside in the outside installation of puncture clamp, the
pipe that wears is installed in the left and right sides of lower sheath box and sleeve shell, and the
pipe that wears can be wrapped in the outside cable through, then with the fixed bolt of fixed strip A and fixed strip B of two sides, play the role of increasing device firmness and protective property, avoid the lack of protective measures, make the protective sleeve rapid aging, lose the protection function, lead to the
metal part of puncture ground wire clamp to
expose directly, easy to take place oxidation,
corrosion, not only influence earthing performance, still can cause
short circuit etc. Fault, threaten the
safe operation of power
system.
