Waterproof treatment method for Elbow Connector

2022-02-10
Whether it is cable or Elbow Connector, they often meet the problem of insufficient length or accidental damage in the process of use, at this time we need to carry out the joint, if the joint is outdoors or in water, it is necessary to do a good job of waterproof treatment of the joint.   

A.Elbow Connector waterproof treatment heat shrink method:

1.Ground Wire (25mm2):
Fix the grounding copper braided belt on the filed steel armor and copper shielding layer with copper tie wire, and solder it securely. At the same time, the copper braided belt should be tinized at 35mm away from the outer sheath.

2.Two Ground Wire:
A 16mm2 copper braid is used for steel armor grounding, and a 25mm2 copper braid is used for three-phase copper shield grounding.  
Note: Do not short-circuit the two ground wires.  (The contact point of the two ground cables shall be separated by wrapping insulation tape or slightly staggered the azimuth of the two ground cables) 

3.Clean the solder ends and cable ties, and wrap them slightly with PVC tape.

4.Put on heat-shrinkable three-finger gloves and heat them evenly to shrink, then put on heat-shrinkable insulating tubes and heat them evenly to shrink.

Note: one end coated with hot melt adhesive is respectively covered to the root of the three-finger sleeve.

B.Elbow Connector waterproof treatment cold shrink method:

1.Insert the end of the copper braid (ground wire) into the three-fork of the cable, wrap it around the three-phase copper shield for a week and lead it out. Then clamp the copper braid to the shield layer and steel armor respectively with two constant force springs, fill the gap between the two constant force springs with filling glue, and wrap the sealant about 35mm under the constant force spring at the steel armor.  

2.If two ground wires are used, use 25mm copper braided belt to wrap the copper shield in a circle, then use a constant force spring to fix the copper shield in a circle, and then turn the head over and fasten it with a constant force spring;  The steel plate is overlapped with 16mm2 copper braided tape, clamped with a constant force spring, then the head is turned over, clamped with constant force spring and finally all fixed.  

Note: Do not short-circuit the two ground wires.  (The contact point of the two ground cables shall be separated by wrapping insulation tape or slightly staggered the orientation of the two ground cables).  

3.Put the cold-shrinkable Breakout into the three-pronged root of the cable, pull out the three-fingered pipe first, shrink naturally, and then pull out the root pipe.  

4.Put the cold-shrinkable insulation pipe into the cable three-phase respectively, and lap the breakout with 25mm. Then pull out the inner pipe of the cold-shrinkable insulation pipe and shrink naturally.  According to the installation length needs, the three-fork part will be initially fixed, and then formally fixed after all completed.  

By default, the Elbow Connector of HUAYI CABLE ACCESSORIES Co.,Ltd. is attached with product installation instructions, you can also ask the sales staff to provide you with product advice and other instructions.
