3. Install insulating tube and restore screen
Clean the surface of insulation, fill the section of connectingpipe with the ethylene propylene self-adhesive tape till the diameteris less than that of the insulation cable; the surface should be flat,and wrap the surface of insulation between both shield layers withthe ethylene propylene self-adhesive tape 1 or 2 layer.
Draw out the insulating tube, set it in the center section, heatup and contract if from the centre to the ends. Because theinsulating tube is very thick, we should heat it up slowly and makeit shrink thoroughly to avoid the gap between lagers.
We should wrap the ends of insulating tube with the self-adhesive tape, the width is about 30mm, and it looks like a flatcone.
Draw out the conducted tube to cover the insulating tube, neatup and contract it, the continuous operation is needed to ensure thegood contact between layers, dispel the gap. Use the EPDM self-adhesive tape to wrap the ends of the conducted tube in order tostrengthen the pressurize.
4. Restore copper screen
Wrap the whole joint with the soft braided copper network,band and weld the copper tape of cable with the ends tightly. Usethe plastic tape and white cloth tape to fasten it in order to protectthe whole joint and make it flat.
