Technical Field

[0001] The utility model relates to the technical field of tubular busbars, and particularly relates to an aluminum tubular busbar with good waterproof and shielding properties. Background Technique

[0002] The tubular busbar, also known as the "tubular cable", is a tubular conductor made of conductive materials such as copper or aluminum, with high electrical conductivity, excellent mechanical strength and good heat dissipation performance, which can meet the requirements of the power system for conductive equipment, and most traditional tubular busbars are composed of a conductive layer, an insulating layer and a wear-resistant layer.

[0003] In order to improve the waterproof performance of the existing tubular busbars, the insulating layer needs to use materials with good waterproof performance. Therefore, a metal shell is mostly used to protect the outermost side of the tubular busbar, but there are still certain defects when in use. Although the metal itself has certain waterproof performance, in a humid external environment, it is prone to rust, which will damage the interior; at the same time, for a single metal sheath, its surface may be worn by the external environment, generating burrs or becoming rough, resulting in poor quality, thus reducing the waterproof performance of the metal sheath, and there is only one insulating layer inside, and its insulation and waterproof strength are average.

[0004] In view of this, in order to study and improve the existing structural deficiencies, the applicant proposes an aluminum tubular busbar with good waterproof and shielding properties to solve the above problems. Content of the Utility Model
