Composite cable for power testing for shallow electric pump

The utility model relates to the category of the cable, in particular to a composite cable for power testing for submersible electric pumps. The purpose of the utility model is to solve the problems that when the cable and the signal of the prior art are separately arranged, the sealing of the downhole equipments such as a packer, etc, is complicated and the cost is relatively high because of the especial processing requirements of the downhole equipments. The composite cable for power testing for submersible electric pumps comprises a high voltage power cable, a signal testing cable, a filler protective sleeve layer and a metal armouring layer. The high voltage power cable is connected together with at least one signal testing cable to be sheathed and produced into the composite cable by the metal armouring layer. The filler protective sleeve layer is filled between the high voltage power cable and the signal testing cable. By compounding the high voltage power cable together with the signal testing cable to produce the composite cable, the utility model realizes the characteristics of high voltage isolation, signal shielding fidelity, water proofing, heat resistance, oil gas resistance, convenient installation, etc. When the utility model is installed, the downhole equipments such as the packer, etc, require no changes, which reduces the through holes of the original signal cable, so that the problem of complicated sealing is solved and the installation is more convenient and fast. As the two cables are compounded into one cable, the stainless steel protective sleeve of the original signal testing cable is removed and the cost is reduced.
