Lidar! Quais cabos industriais são necessários em um grande projeto de petróleo e gás?

Em projetos de petróleo e gás em larga escala, industrial cables are not just accessories—they are the “nervous system” and “blood vessels” of the entire operation. Seja uma plataforma de perfuração offshore, a refinery, or a sprawling pipeline system, the reliability of cables directly impacts equipment performance and safety.

This article ZMS Cable will provide a detailed overview of the different types of industrial cables used in oil and gas projects, their technical requirements, padrões, real-world applications, and tips for selecting the right cables. This guide will help you make informed decisions and ensure the safe and efficient execution of your project.

Types of Industrial Cables in Oil and Gas Projects

Industrial cables used in oil and gas projects must be able to withstand extreme conditions—high temperatures, mechanical stress, exposição química, and sometimes even explosion risks. Below is a breakdown of the essential types of cables needed for various applications:

um. Cabos de alimentação

Power cables are used for distributing electrical power to all types of equipment, from machinery to lighting and emergency systems. These cables come in various voltage ratings depending on the power requirements of the project.

Low Voltage (LV) Cabos de alimentação: Used for smaller systems, typically up to 1kV. Common in lighting circuits and low-power equipment.

Medium Voltage (MV) Cabos de alimentação: These cables cover voltage ratings from 1kV to 35kV, powering larger equipment such as motors, pumps, and large compressors.

High Voltage (Hv) Cabos de alimentação: Required in larger offshore platforms or remote oil and gas sites, with voltages exceeding 35kV.

Key Specifications:

XLPE (polietileno reticulado) insulation for durability in extreme temperatures.

Flame-retardant, low smoke zero-halogen (LSZH) sheaths for fire safety in confined spaces.

Padrões: CEI 60502, Bobagem 6622, IEEE 1580

b. Control Cables

Control cables are used to transmit signals and control functions between various equipment and systems. These cables play a vital role in remote control, automation, and safety systems.

Multi-core cables with individual shielding are used to minimize electromagnetic interference (EMI), ensuring precise signal transmission.

Cables are designed to withstand oil, água, e exposição química, making them suitable for use in harsh environments like drilling rigs and offshore platforms.

Key Specifications:

Shielding to prevent interference.

Flame-retardant and low-smoke properties.

Flexible designs for ease of installation in tight spaces.

Common Types: CY, YY, SY, LIYCY cables

Padrões: CEI 60092-376, Bs um 50288-7

c. Instrumentation Cables

Instrumentation cables are essential in transmitting data from field instruments (such as sensors and gauges) to control systems. They ensure real-time data communication and process control, especially in environments where safety and precision are paramount.

Individual and overall shielding is often used to protect the signals from electromagnetic interference.

LSZH (Baixa fumaça e zero halogênio) sheaths are frequently chosen in environments where safety is a concern, as they emit minimal smoke and no toxic gases in case of fire.

Key Specifications:

High resistance to temperature fluctuations, óleos, and chemicals.

Minimal signal loss over long distances.

Padrões: CEI 60092-376, Bs um 50288-7

d. Cabos de fibra óptica

As the oil and gas industry becomes more digitalized, cabos de fibra óptica are increasingly used for high-speed communication, remote monitoring, and data transmission. They offer several advantages over traditional copper cables:

Immunity to electromagnetic interference (EMI), making them perfect for noisy industrial environments.

High bandwidth and long-distance data transmission are critical for SCADA systems, CCTV systems, and real-time data exchange between onshore and offshore locations.

Key Specifications:

Single-mode or multi-mode fiber options depending on the application.

Waterproof and resistant to harsh environmental conditions.

Usage: SCADA systems, communication between offshore and onshore facilities, real-time monitoring of remote sites.

e. Cabos Blindados

In areas prone to mechanical damage—such as drilling rigs, offshore platforms, or even underground pipelines—cabos blindados are used to protect the cables from external impacts, physical wear, and even rodent damage.

SWA (Steel Wire Armored) cables are the most common type used in rugged, high-impact environments.

AWA (Aluminum Wire Armored) e STA (Steel Tape Armored) cables are also used, depending on the specific requirements.

Key Specifications:

Armoring provides mechanical strength and protection.

Resistance to crush, abrasão, and even exposure to oils and chemicals.

Usage: Power distribution, sistemas de controle, communication lines in high-risk zones.

How to Choose the Right Industrial Cable for Oil & Gas Projects

When selecting industrial cables for an oil and gas project, the following factors must be considered to ensure the cables meet the demands of the environment and system requirements:

um. Condições Ambientais

Temperature Resistance: Offshore rigs or desert-based oilfields experience extreme temperatures, so cables with insulation such as XLPE or silicone rubber are ideal for high-temperature environments, while cables with special materials like PVC may be used in colder areas.

Resistência química: Many oil and gas projects involve exposure to oils, ácidos, solventes, and other corrosive substances. Cables with specialized coatings and insulations like EPR (Borracha de etileno propileno) or CSP (Polietileno Reticulado) are recommended for chemical environments.

Water Resistance: For subsea operations, cables need to be water-blocked, have water-tight sheathing, and provide reliable performance in wet conditions. Offshore platforms require cables with special waterproof designs.

b. Fire Safety and Hazardous Zone Classification

In hazardous zones (Zone 0, Zone 1, and Zone 2), fire-resistant e cabos retardadores de chama are mandatory to ensure the safety of personnel and prevent disasters. These cables must meet:

Flame-retardant properties to prevent the spread of fire.

Low smoke, zero halogen (LSZH) for better safety in case of fire.

ATEX or IECEx certification for operation in explosive atmospheres.

c. Mechanical Strength

For installation in harsh environments, such as those with heavy machinery or potential physical impact, armored cables with high tensile strength e resistência ao impacto are essential. These cables are designed to withstand physical stress, rodent attacks, e abrasão.
