In recent years, with the rapid development of my country's economic construction, copper, as the second largest strategic material in my country after oil, has seen a rapid increase in consumption:
However, due to the soaring copper price and the fact that my country is rich in aluminum but lacks copper resources, aluminum is increasingly used in the power industry:
The Development and Reform Commission and the Ministry of Industry and Information Technology have also clarified the strategic direction of "saving copper with aluminum": The strategic direction of "saving copper with aluminum" is not only
The direction of the power cable industry is also the direction of all related industries and is an international trend:
Reliable electrical connections of aluminum conductors are more demanding than those of copper conductors, primarily due to the material's oxidative and mechanical properties:
Therefore, it is necessary to conduct additional tests based on the copper conductor test procedures to fully test the performance of the aluminum conductor terminal blocks to ensure
Ensure its safety:

Terminal Blocks
1 Scope
This document specifies threaded or non-threaded type electrical and mechanical connections for mounting on a bracket, primarily for industrial or similar purposes:
Requirements for terminal blocks with screw-type clamps: This document can be used for terminal blocks for connecting aluminum conductors or connecting aluminum conductors to copper conductors:
This document is applicable to connection cross-sectional areas of 2:5mm2~300mm2 (AWG12kcmil~600kcmil), with or without special
Terminal blocks for processed round wires, intended for use with rated voltages not exceeding 1000VAC (not exceeding 1000Hz) or 1500VDC
In the circuit:
This document can be used as a terminal block for aluminum conductors that do not meet the requirements of GB/T 3956 (e:g: less than 10mm2, flexible or other materials):
This document can also be used as a guide for other types of aluminum conductor terminal blocks other than straight-through terminal blocks (e:g: partially insulated
terminal block with insulation):
Note 1: AWG is the abbreviation of "American Wire Gauge":
kcmil=1000cmil:
1cmil = 1 circular mil = the area of a circle with a diameter of 1 mil:
1mil=1/1000in:
This document does not apply to the following clamping elements:
--- Clamping parts specially designed for any other type of switchgear and controlgear;
--- Clamps connected by crimping, brazing, soldering or welding;
--- Clamping parts for digital and signal circuits;
--- Clamping parts for flat quick-connect terminals, insulation piercing connectors and twist-on connectors: The requirements for these clamping parts shall be considered as independent
Some are under consideration:
NOTE 2 If special types of wire are used that require special processing (e:g: coated wire), this document can be used as a guide:
NOTE 3 In some countries, national regulations for installation rules allow different cross-sectional areas: For internal wiring (inside the enclosure), other regulations or product standards apply:
Note 4: IEC 60947-7-1:2009 applies only to the connection of copper conductors:
Note 5: In the United States, UL1059 applies; in Canada, CSAC22:2No:158 applies:
When referencing IEC 60947-1:2020, the term “clamp” is used in this document instead of “terminal”:
