CAMESA began manufacturing wire rope in Mexico City in 1958 and two years later was producing its own high carbon steel wire. In 1970 development work started to produce the electromechanical (EM) cables used by the oil field wire-line service companies.

In 1975 CAMESA opened a plant to exclusively manufacture EM cables incorporating the latest extrusion and armoring technology.All cables are produced with high-speed tubular armoring machinery. CAMESA has also developed several new manufacturing techniques including multi-stage pre-forming and continuous hot pre-tensioning*. These new techniques contribute to the overall uniformity and quality of our cables.

CAMESA is continuously developing cables for new applications. Engineers are actively involved in developing newand improved products and manufacturing techniques for the next generation of electromechanical cables.

CAMESA has a rigorous quality control system covering incoming raw materials, all production processes and finished products to assure cables free of manufacturing defects and excellence in performance. The AMERICAN PETROLEUM INSTITUTE certifies CAMESA’S quality system.

CAMESA iscommitted to being number one in customer service and support. CAMESA is also committed to providing our customers with a reliable product that will exceed their needs. With an experienced team of support staff and with inventories at several locations around the world, CAMESA is there for you.

Cable Features
Cables are armored with special galvanized improved plow steel wires. Tensile strength of each wire lies in the range of 270 to 300 KPSI. Each wire .035” in diameter or larger has a coating of zinc in excess of 0.5 oz/sq.ft of surface area. Wires less Than .035” in diameter have in excess of 0.2 oz./sq.ft. of surface area.No butt welds of the original rod or wire during or after the final drawing process are allowed. No splices of any conductor are allowed in any CAMESA cable. All armor wires are preformed during the manufacturing process Average preform value 75%+5%-5%. All multi-conductor cables are subjected to continuous hot pre-tensioning, a patented CAMESA process. Resistance and capacitance values for eachconductor within a layer are within 5% of the minimum value measured for that layer. Each newly manufactured CAMESA cable is tested to determine that it meets the catalog rated minimum breaking strength. This test is carried out with no cable rotation allowed. Each layer of armor wires is coated with a corrosion inhibitor. The catalog temperature ratings of CAMESA cables apply for the bottom holetemperatures of ordinary oil/gas well logging situations. “Ordinary” Here refers to situations in which borehole temperature increases with depth to a maximum at the bottom of the borehole. Temperature ratings should be lowered when the cable is used in highly deviated wells, in producing or geothermal wells with high temperatures nearer the surface. All cable diameter values shown in the catalogare nominal and measured under 100-300 lbs. Spooling tension onto shipping reel Electrical resistance and capacitance values shown in the Camesa catalog are nominal or typical values. All values have been corrected to 20 degrees C. During the manufacturing process a strict quality control program is enforced. Each cable is given a complete electrical and mechanical test to confirm that it meets orexceeds catalog specification. This CAMESA final inspection report is available to the customer upon request. The maximum working tension of any CAMESA cable should not exceed 50% of the published catalog breaking strength.
