Load-bearing Propection Cable

• Applicable Manufacturing Standard

JB/T3302-1999

This product is a steel-wire armored oilfield exploration cable designed for electrical measurement under mechanical load. It is applied to well logging, perforation and coring operations in various oil and gas wells. It can also be used for ocean surveys, hydrological measurements in rivers, harbors and water conservancy projects, coalfield geological exploration, geothermal well logging, etc. It serves as a connecting wire for suspended load instrument measurement.

• Working Performance

The diameter of winch roll should be no less than 400mm.The bending radius of wellhead pulley, aerial pulley,and ground pulley should be no less than 230mm. The pulley groove should suit well with cable outer diam- eter. The D.C. conductor resistance should be no more than 36Ω/Km；It could endure voltage test of A.C. 50Hz，1000V for 1 minutes without puncture between conductor and armor.
