A kind of compound electric cable of submersible pump, including three cores being set up in parallel, the core outer wrap have armor, institute Stating also includes 1 or 2 external diameter and the core external diameter identical metal tube in armor, the metal tube and the core are arranged side by side Set and the both sides of the metal tube are adjacent with the core.

As a kind of optimal technical scheme of the present utility model, the core is followed successively by conductor, insulating barrier, shield from inside to outside Jacket layer and a of resistance to oil reservoir.

As a kind of optimal technical scheme of the present utility model, one is each provided with positioned at the both sides of the Zhong Jian core Metal tube.

As a kind of optimal technical scheme of the present utility model, the side of the Zhong Jian core is provided with a gold Category pipe.

As a kind of optimal technical scheme of the present utility model, the conductor is that solid metallic conductor or stranded wire are led Body.

As a kind of optimal technical scheme of the present utility model, the insulating barrier is made up of EP rubbers material.

As a kind of optimal technical scheme of the present utility model, the restrictive coating is made up of metallic lead.

As a kind of optimal technical scheme of the present utility model, oil resistant is provided between the metal tube and the armor Layer b.

As a kind of optimal technical scheme of the present utility model, the metal tube is stainless steel tube.

The beneficial effects of the utility model are：

By above-mentioned technical scheme, it is provided for filling the metal tube of auxiliary agent between core, can be in filling auxiliary agent While substantially reduce the temperature of core, the too high influence electrical performance of its temperature is prevented, so as to improve working stability degree and make With the life-span, meanwhile, metal tube can play the mechanical performance for strengthening cable, and because metal tube both sides are adjacent with core, can It is effective against the effect of down-hole high pressure.
