Single Side Alu EL Composite Aluminium Tape 0.25mm For Fibre Cable Shielding
0.25mm Alu EL single side composite tape For Fibre Cable Shielding
No more than two joints are allowed in the same disc (reel), but butt welding joints are allowed, one joint is allowed if the length is less than 1.4km, and two joints are allowed if the length is 1.4km or more.The thickness of the joint should not exceed 15 times of the original thickness, the plastic layer of the joint should be restored, the joint should be marked, and the distance between the two joints should not be less than 305m.The tensile strength of the aluminum-plastic composite belt with joint should not be less than 85% of the adjacent aluminum-plastic composite belt without joint.The DC resistance of the 1M long aluminum-plastic composite belt with a connector should not be greater than 110% of the DC resistance of the adjacent 1m long aluminum-plastic composite belt without a connector.
