1. Rubber power cord for load detection: the outer diameter is usually less than 12mm; the length is long and the single length is more than 3500m; the oil and gas resistance is 120MPa (1200 times the atmospheric pressure); the high temperature resistance is above 100 ℃; anti-interference 2. Tensile strength: more than 44KN; wear-resistant and resistant to hydrogen sulfide gas; all armored steel strands will not spread apart when broken, otherwise it will cause waste wells.
1) Conductor with soft structure and tin plating; 2) High temperature resistant polypropylene, ethylene propylene rubber or fluoroplastic for insulation; 3) Semi-conductive material for shielding; 4) High strength galvanized steel wire for armoring; 5) Special manufacturing technology.
2. Perforated rubber power cord: the cross-sectional area and tensile force of the hole are large, wear-resistant, vibrating and not loose.
1) Medium soft structure for conductor; 2) Polypropylene, ethylene propylene rubber or other high temperature resistant materials for insulation; 3) Conductor, insulation and armor are of correct size.
3. Surveying rubber power cords for coal fields, non-metals, metals, geothermal, hydrology, underwater, etc.
1) Reinforced core and inner armor; 2) Conductor is soft copper wire; 3) Ordinary rubber for insulation; 4) Neoprene sheath; 5) Metal or non-metallic armor for special cases; 6) Underwater rubber power supply The cable should use coaxial rubber power cord; 7) The comprehensive detector should have power, communication and other functions.
4. Rubber power cord for submersible oil pump: the outer diameter of the tubing is small, and the outer size of the rubber power cord is required; the depth of the well is increased, the power is large, the insulation is resistant to high temperature, high pressure, and the structure is stable; good electrical performance, good insulation performance, and small leakage current; Long life, stable structure, reusability; good mechanical properties.

1) For small and medium-sized oil pipes, flat rubber power cords are adopted to ensure small external dimensions; solid and large cross-section conductors are used: twisted conductors and round rubber power cords; 2.) polyimide for connecting rubber power cord cores -Fluorine 46 sintered wire, ethylene-propylene insulation; heat-resistant insulation of ethylene-propylene and cross-linked polyethylene for power rubber power lines; 3) oil-resistant high temperature resistant materials such as neoprene rubber and chlorosulfonated polyethylene for sheath, lead sheath Etc .; 4) Use chain armor; 5) Halogen-proof structure, add halogen-proof sheath to bare armor.
