內容概要

　　From using point of view, this book go into particulars
all;erformance of the material and construction on XLPE insulated
power cablefrom theoretical and performance calculation, and tell
about the option,installation, operation, maintain, test on site,
hand-over and prevention test, teststandard and standard demand
over this base. This book also introduce the somemanagerial
experiences used to XLPE insulated power cable on the Electric
Power Supply Bureau, and analyse the development tendency of XLPE
insulated cable.
　　The book is a studied and worked handbook of engineer necessity
used onthe XLPE insulation cable, a reference book of engineer at
the Electric PowerSupply Bureau in China.

章節(jié)摘錄

　　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. 　　……
