— Full-scenario signal transmission guarantee for oil exploration, drilling platforms, refining & petrochemical processing, and oil & gas storage & transportation
The oil and gas industry is widely regarded as the lifeline of modern industry. Its operating environments range from onshore oil fields and offshore drilling platforms to refinery & petrochemical units and oil & gas storage & transportation stations, all of which present extremely harsh conditions. Since flammable and explosive gases and chemically corrosive substances are pervasive throughout the production process, stringent requirements are imposed on the transmission accuracy and operational safety of instrumentation and actuator signals. As the “nervous system” connecting field devices to the control center, the reliability of cables directly affects both safety and economic performance in oil and gas production.
Leveraging nearly 50 years of experience in manufacturing wires, cables, and instruments, Anhui Tiankang (Group) Co., Ltd. deeply addresses the special cable needs of the oil and gas industry. Our series of instrumentation cables, with excellent anti‑interference capability, flame‑retardant and fire‑resistant properties, oil and corrosion resistance, and intrinsic safety, have been widely used in domestic and international oil and gas drilling platforms, large‑scale refinery & petrochemical units, and national pipeline storage and transportation projects. The company has been listed among the Top 500 Chinese Manufacturing Enterprises for many consecutive years. Our products are exported to more than 40 countries and regions, including Russia, Iran, Kazakhstan, Saudi Arabia, Italy, and Brazil. We are a long‑term strategic supplier to many leading petrochemical companies, such as CNPC, Sinopec, and CNOOC.
1. Core technical requirements for instrumentation cables in oil & gas scenarios
Unlike conventional industrial environments, the severe conditions of the oil and gas industry impose the following key standards on the design and manufacture of instrumentation cables:
Flame retardance and fire resistance – In the event of a fire in oil & gas facilities, cables must maintain circuit integrity for a certain period. Tiankang instrumentation cables strictly comply with IEC 60332‑1 and Class A bunched flame retardance standards; some products achieve 90 minutes of fire resistance.
Intrinsic safety protection – For hazardous explosive zones (Zone 0/1/2), we provide intrinsically safe cables compliant with national standard GB 3836, preventing dangerous sparks through proper electrical parameter matching.
Superior electromagnetic shielding – Oil & gas automation sites are often accompanied by variable frequency drives, making electromagnetic interference inevitable. For 4‑20 mA analog signals, shielding coverage density exceeds 90%, effectively stabilizing PV node values.
Wide temperature range – Products can meet requirements from ‑40 °C cold‑resistant cables for arctic regions to 200 °C flexible cables with fluoroplastic insulation for environments around coking furnaces.
High‑grade mechanical protection – Depending on field stress and the need for rodent/ant protection, galvanized steel wire armoring or double steel tape armoring is available; for desert areas such as the Middle East, special UV‑resistant and rodent‑resistant jackets are designed.
Oil and chemical resistance – Oil, grease, and chemical media are everywhere in oil & gas sites. Our cable jackets use special oil‑resistant formulations to ensure that they do not swell or crack under long‑term exposure to hydrocarbons.
Low smoke, zero halogen, and environmental friendliness – Cables used in enclosed control rooms, tunnels, and offshore platforms feature low smoke zero halogen (LSZH) characteristics. Light transmittance in smoke during combustion exceeds standard values, buying precious time for personnel evacuation on oil & gas platforms.
2. Complete series of instrumentation cables for oil & gas from Anhui Tiankang
With over 30 years of experience in manufacturing specialty cables, Anhui Tiankang designs and produces a full range of instrumentation cables for the oil and gas industry, widely applicable to sensor signals, transmitter power supply, and fieldbus communications. According to the Design and Selection Standards for Instrumentation Cables in Petrochemical Industries and the Standard for Computer and Instrumentation Cables for Petroleum Equipment, our main products include the following types:
Intrinsically safe instrumentation and control cables (IS cables) – Suitable for hazardous areas with explosive gas mixtures (e.g., methane, hydrogen sulfide, gasoline vapor) and oil storage & transfer centers. These cables feature low capacitance and precisely matched electrical parameters, effectively suppressing energy storage discharge. Together with safety barriers, they form a complete explosion‑proof loop, suitable for signal transmission in various hazardous zones.
Computer and DCS signal cables – Employ a composite structure of individually shielded twisted pairs plus an overall shield, providing efficient suppression of RF interference. Characteristic impedance tolerance is controlled within ±15 Ω, making them especially suitable for accurate long‑distance transmission of analog signals from DCS, PLC, ESD, and other control systems.
High‑temperature‑resistant and corrosion‑resistant shielded instrumentation cables – Designed for high‑temperature environments such as coking units, catalytic cracking, and boiler flame monitoring. Fluoroplastic (FEP/PFA) or silicone rubber insulation is used, with continuous operating temperatures up to 200 °C (fluoroplastic) or 180 °C (silicone rubber), ensuring accurate signal transmission in high‑temperature refinery and petrochemical areas.
Armored / non‑armored general instrumentation signal cables – Suitable for direct burial, overhead, or conduit installation in refinery pipelines and drilling platforms. The armor layer and tinned copper wire braid shielding effectively prevent mechanical damage and rodent attack; the jacket material meets multiple test standards for sunlight resistance, oil resistance, and flame retardance.
Full range of compensating and extension cables – Accurately matched to thermocouple types (K, E, S, J, T, N). Used for cold‑junction extension of thermocouples in petrochemical units, they ensure high‑accuracy transmission of thermoelectromotive force, providing reliable data for furnace wall temperature monitoring.
RS‑485 / Modbus industrial data bus cables – Characteristic impedance is strictly controlled to 120 Ω. With low‑capacitance materials and tinned copper braid shielding, they meet the reliability requirements for data transmission in oil platform and oilfield automation RTU (remote terminal unit) systems.
