Description

A kind of cable that waterproofness is strong

Technical field

The utility model relates to field of cable technology, specially a kind of cable that waterproofness is strong.

Background technique

Cable is usually every group by several or the cable of similar rope that several groups of conducting wires [every group at least two] are twisted Mutually insulated between conducting wire, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Multi rack is located at In the air or it is mounted in underground, the bottom, is used for telecommunication or power Transmission.1832, tsarist Russia's army officers were permitted woods lattice and are buried telegraphy line Each other with, with being placed in glass tube, here it is an earliest in the world undergrounds after rubber-covered between underground, six conductors Cable is placed in the insulated conductor constituted in sealing sheath by the conducting wire center of one or more mutually insulated.Protection can be added outside it Coating is used for transmission, distributes electric energy or transmission electric signal.The difference of it and common wiring is mainly that cable dimension is larger, knot Structure is more complex, and existing cable can generally be embedded in underground, often makes because its waterproof performance is bad to it with contact with moisture Very big influence is caused with the service life and using safe.

The strong cable of traditional waterproofness does not have good waterproof effect, the moisture after Underground Long-term and contact with moisture It is easy to damage wire core, whole security performance greatly reduces, reduces its service life, increases use The loss of person, just long-range to consider do not have good superiority, protective value is not strong, and overall utility is not strong.
