Import Downhole Sensor Cable, Downhole Wireline Cable — Buy in wholesale FOB from Supplier in China

The Downhole Sensor Cable from Qingdao Banghua Wire & Cable Co., Ltd is a specialized wireline cable designed for real-time data transmission in high-pressure, high-temperature downhole environments. It features a central conductor core surrounded by layered insulation and shielding, with an outer jacket rated for temperatures up to 175°C and pressures exceeding 15,000 psi. The cable supports analog and digital signal integrity over distances up to 5,000 meters, with a typical outer diameter range of 8.5 mm to 14 mm depending on core count and shielding configuration.

The conductor is typically made from tinned copper, with insulation composed of fluoropolymer or cross-linked polyethylene to maintain dielectric stability under thermal stress. Shielding includes foil and braided copper for EMI rejection, standard in oilfield wireline applications. The jacket material is usually thermoplastic elastomer or chlorinated polyethylene, offering resistance to drilling fluids, hydrogen sulfide, and mechanical abrasion. These material choices align with industry norms for downhole cables used in ESP systems and wireline logging tools.

This cable is primarily used in oil and gas well monitoring, geothermal exploration, and water well logging applications where continuous data feedback is critical. Buyers include drilling contractors, well service companies, and geophysical survey firms operating in the Asia-Pacific, Middle East, and Latin American markets. Trade terms are typically FOB Qingdao Port, with packaging in wooden reels or steel drums. Custom lengths are available upon request, but standard reels range from 500 to 2,000 meters per unit.
