Disclosed is a new submersible oil pump connection cable, comprising an inner insulating layer made of high temperature resistant insulation material PFA, an outer insulating layer made of modified polypropylene, a closed layer composed of aluminum-plastic tape (longitudinally wrapped), a shield made of modified polypropylene, an inner protective pad layer made of high-density thick cotton cloth and single-core cables which use single-strand oxygen-free copper wires as conductors. Three single-core cables are laid in parallel; an outer protection layer formed by runway-type armored steel tape; the inner insulating layer and the outer inner insulating layer from a combined insulation; the PFA material of the inner insulating layer has a more stable performance under high temperature and the working temperature can be raised to 250 Celsius system; the modified polypropylene of the outer insulating layer can maintain good insulation performance even in the softening or liquefaction state; the longitudinally wrapped aluminum-plastic tape of the closed layer is of sealing and shielding effects.
