Scotch 23 ApplicationsRUBBER TAPES
u PRIMARY ELECTRICAL INSULATIONfor splicing and terminating up to 69 kV on all
solid dielectric cables (i.e. XLPE, EPR)
u This means you can replace an XLPE or EPR insulation of a MV cable by wrapping several layers of # 23 tape stretched about 50-70% and half-overlapped until you reach the required insulation thickness. IMPORTANT is to obtain an air void free insulation layer due to self-fusing feature of #23 tape.

Scotch 130C ApplicationsRUBBER TAPES
u PRIMARY ELECTRICAL INSULATIONfor splicing and terminating up to 69 kV on all
solid dielectric cables (i.e. XLPE, EPR)
u You can use #130C tape the same as #23 tape. Difference is such that #23 tape is more practical when used on 3 core cables splices than using #130C tape, For 3 core splices you have to use short strips of the tape rather than applying directly from a roll because a roll can not be easily passed between the cable cores. # 23 tape will not have any problems here, but #130C tape will, Because #130C has a sticky side and it sticks to itself and makes it difficult when you tr y to pass its strips between the cores.
u Therefore, #130C is used more with 1 core cables/splices.

Scotch 130C ApplicationsRUBBER TAPES
u PRIMARY ELECTRICAL INSULATIONfor splicing and terminating up to 69 kV on all
solid dielectric cables (i.e. XLPE, EPR)
u #130C tape has higher thermal conductivity than #23 tape. Therefore it is preferable to use it for splicing at higher voltages. Higher voltage means more layers of insulation tape and thicker insulati on and in this case #130C tape offers the advantage of dissipating the heat of the splice to outside bette r at its operation and increasing the life time of splic e. There are examples of customer made splice designs with #130C tape even higher than 69 kV due to this property (high therm. cond.).

u Scotch 13 self-fusing tape is wrapped over the insulation made by using Scotch 23 tape as half-overlapped and with printed side coming out.

Scotch 70 ApplicationsRUBBER TAPES
u SEALING TOP END (on cable lug) OF QT II SILICONE TERMINATION
u HIGH TEMPERATURE RESISTANCE (180 °C)(other than termination applications)
u Scotch 70 self-fusing tape is made of silicone rub ber, like the silicone material of QT II termination. Its lay ers fuses to itself and also almost to the silicone material of QT II and provides an excellent seal.
u It is a high track resistance material (resistance t o surface currents) like QT II insulation body. This means it also resists to surface currents on the termination and adds to long life of the termination.
u Also used for other applications while Scotch 70 ta pe has 180 C continuous operating temperature .
