Aluminum alloy groove connection

Aluminum alloy groove connection 
 
Everyone will choose aluminum alloy wire groove when choosing wire groove, aluminum alloy wire groove is strong and practical. And after installation is more neat and beautiful, the aluminum alloy groove should be how to connect it ? What should be paid special attention to ? 
 
Aluminum alloy groove connection 
 
1, groove neat no bending deformation, no burr on the inner wall, the interface is dense and straight, a variety of accessories complete. 
 
2 、 The groove connection should be neat, the interface is dense and straight, the groove cover should be neat, no warping angle, the outlet is reasonable. 
 
3.When the groove goes through the deformation joint, the groove itself should be disconnected, the groove is connected with the connecting plate, which cannot be fixed, and the protective ground wire needs to have the margin of compensation. The groove CT300 * 100 is fixed with one bolt, and the CT400 * 100 or more must be fixed with two bolts. 
 
4, the non-conductive part of the non-metallic wire groove should be connected to the corresponding jumper, so that it becomes a whole, and do a good job of overall connection. 
 
5 、 Laying in the shaft groove and shuttle different fire zone groove, according to the design concept of standard parts set fire blocking specific measures. 
 
6, straight end steel groove total length is higher than 30 m plus expansion joint, cable groove across the deformation joint with compensation equipment. 
 
7, between the metal cable slot and the total length of the bracket should not be less than 2 and ground or ground connection. 
 
8, non-galvanized cable slot connecting plate at both ends of the copper core grounding wire connection, grounding wire can be small section is not less than bvr-4mm. 
 
9, galvanized cable slot mutual connection plate at both ends
