For preventing cable termination earth connection from corroding, extending earth connection useful life, therefore needing to improve cable termination earth connection.
[utility model content]
In view of this, for overcoming the deficiencies in the prior art, the utility model provides a kind of cable termination Special grounding wire, can prevent cable termination earth connection burn into from extending earth connection useful life.
A kind of cable termination Special grounding wire, described cable termination Special grounding wire comprises interlude and first, second termination, described interlude is the insulated conductor of circular section, described first termination is the copper Wiring nose for being connected with earthing device, described second termination is the flat cross section termination of welding with cable termination, described flat cross section termination comprises the insulated part and exposed part that are connected with described interlude, and described exposed part is through warding off tin.
Wherein at least one preferred embodiment, described second termination is single flat cross section termination.
Wherein at least one preferred embodiment, described second termination is the flat cross section termination of three deciles.
Wherein at least one preferred embodiment, the length of the described exposed part of described second termination is not less than cable termination length.
Wherein at least one preferred embodiment, the length of described exposed part is 20mm.
Wherein at least one preferred embodiment, the length of described cable termination Special grounding wire is 700 ± 100mm.
Wherein at least one preferred embodiment, described interlude is circular section insulated conductor, and the core section of described interlude is long-pending is not less than 16mm
2.
Cable termination Special grounding wire of the present utility model is made up of profiled-cross-section termination and copper Wiring nose, stube cable terminal and earthing device respectively, the exposed part of profiled-cross-section termination is through warding off tin, not only specification cable terminal makes earth connection, also has important effect useful life to preventing earth connection burn into from extending earth connection.
[accompanying drawing explanation]
