Abstract

The utility model relates to a U-shaped copper-aluminum composite bar. The U-shaped copper-aluminum composite bar includes a copper-aluminum composite bar body (1). The copper-aluminum composite bar body (1) comprises a copper pipe (2) and an aluminum layer (3); the aluminum layer (3) is filled in the copper pipe (2); and the copper-aluminum composite bar body (1) is U-shaped. According to the U-shaped copper-aluminum composite bar of the utility model, the aluminum layer (3) is filled in the copper pipe (2), thereby greatly reducing production cost of enterprises, and ensuring conductive performance; and further, with the U-shaped design adopted, placing space is saved to a great degree.

Description

U-shaped copper aluminium composite bar

Technical field

The utility model relates to a kind of U-shaped copper aluminium composite bar.

Background technology

Copper bar is a kind of conducting heavy current product, is applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct, also is widely used in the super-large current electrolysis for production engineerings such as metal smelt, electrification plating, chemical industry caustic soda.But we have the advantages such as the low bending degree of resistivity is large by electrician's copper bar of supply.General copper bar is to be made of copper at present, and production cost is high, and copper bar generally all is to be strip in addition, and is long, takes up space very much.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, the U-shaped copper aluminium composite bar that a kind of conserve space is provided and reduces production costs.

The purpose of this utility model is achieved in that

A kind of U-shaped copper aluminium composite bar comprises copper aluminium composite bar body, and described copper aluminium composite bar body comprises copper pipe and aluminium lamination, is filled with aluminium lamination in the described copper pipe, and described copper aluminium composite bar body is U-shaped.

Compared with prior art, the beneficial effects of the utility model are:

The U-shaped copper aluminium of the utility model composite bar filling aluminum in copper pipe, the one-tenth that greatly reduces enterprise produces cost, and has guaranteed electric conductivity, and U-shaped being arranged on saved placement space to a great extent in addition.

Description of drawings

Fig. 1 is the structural representation of the U-shaped copper aluminium of the utility model composite bar.

Fig. 2 is the sectional view of Fig. 1.

Wherein:

Copper aluminium composite bar body 1

Copper pipe 2

Aluminium lamination 3.

Embodiment

Referring to Fig. 1 and Fig. 2, the U-shaped copper aluminium of the utility model composite bar comprises copper aluminium composite bar body 1, and described copper aluminium composite bar body 1 comprises copper pipe 2 and aluminium lamination 3, and described copper pipe 2 cross sections are the round rectangle shape, are filled with aluminium lamination 3 in the described copper pipe 2.

Described copper aluminium composite bar body 1 is U-shaped.

At copper pipe 2 interior filling aluminium laminations 3, because the price of aluminium is lower than copper, thus greatly reduce production cost, and not decline of electric conductivity, can normally use.Copper aluminium composite bar body 1 is U-shaped in addition, and so just making described copper aluminium composite bar is not strip, has saved placement space.

Claims (1)

1. U-shaped copper aluminium composite bar, comprise copper aluminium composite bar body (1), it is characterized in that: described copper aluminium composite bar body (1) comprises copper pipe (2) and aluminium lamination (3), is filled with aluminium lamination (3) in the described copper pipe (2), and described copper aluminium composite bar body (1) is U-shaped.
