ればならない。1 to 11 This type of cable should have the smallest possible diameter so that it can be easily inserted into the valving and can be wound over a length on the cable drum. These cables are also subject to three extremely large stresses: mechanical stresses resulting from well pressure, which can reach more than 350 bar; chemical stresses, which vary depending on the type of oil flow; and chemical stresses, which can reach more than 150 degrees Celsius. It must be able to withstand the thermal stresses that occur.

く、さく井の底の高温に対する保護も不十分である。An example of an oil and gas well boring control cable of this kind is known, inter alia, from British patent document GB-2027553. This known cable consists of a central electrical conductor and two lateral stress bodies, these three elements being surrounded by a flat elastomeric sheath. This cable has a flat elastomer sheath, which minimizes its bulk, and it has two stress-resisting bodies on the sides, making it resistant to crushing. Protection against high temperatures at the bottom is also insufficient.
