1. Load-bearing rubber power cord: the outer diameter is usually less than 12mm; the length is long, a single length of more than 3500m is supplied; oil and gas resistance, water pressure resistance 120MPa (1200 times atmospheric pressure); high temperature resistance: 100℃ or more; , Tensile strength: above 44KN; wear-resistant, resistant to hydrogen sulfide gas; all armored steel strands will not spread when they are broken, otherwise it will cause a waste well.
structure:
(1) The conductor has a flexible structure and is tin-plated;
(2) High temperature resistant polypropylene, ethylene-propylene rubber or fluoroplastics for insulation;
(3) Semi-conductive materials for shielding;
(4) High-strength galvanized steel wire for armor;
(5) Use special manufacturing technology.
2. Perforated rubber power cord: large hole cross-sectional area and tensile force, wear-resistant, vibrate, and not loose.
structure
(1) Medium flexible structure for conductor;
(2) Polypropylene, ethylene propylene rubber or other high temperature resistant materials for insulation;
(3) The size of conductor, insulation and armor is correct.
3. Rubber power cords for coal field, non-metal, metal, geothermal, hydrological, underwater, etc. surveys.
structure:
(1) Reinforced core and inner armor;
(2) The conductor is soft copper wire;
(3) Ordinary rubber for insulation;
(4) Sheath neoprene rubber;
(5) Metal or non-metal armor is used in special circumstances;
(6) Coaxial rubber power cables should be used for underwater rubber power cables;
(7) The comprehensive detector should have functions such as power and communication.
4. Rubber power cord of submersible pump: the outer diameter of the tubing is small, the outer size of the rubber power cord is required to be small; the depth of the well is increased, the power is large, the insulation is required to withstand high temperature, high pressure, and the structure is stable; good electrical performance, good insulation performance, and small leakage current; Long life, stable structure, reusability ability; good mechanical properties.
(1) For small and medium-sized oil pipes, use flat rubber power cords to ensure small dimensions; solid conductors with large cross-sections: stranded conductors, round rubber power cords;
(2) Use polyimide-fluoro46 sintered wire for rubber power cord core, ethylene propylene insulation; power rubber power cord uses ethylene propylene, crosslinked polyethylene heat-resistant insulation;
(3) Oil-resistant neoprene rubber, chlorosulfonated polyethylene and other oil-resistant and high-temperature resistant materials, lead sheath, etc.;
(4) Use chain armor;
(5) Halogen-proof structure, with a halogen-proof sheath added to the bare armor.
