EA402 913-402-000-012-A2-E040-F0-G000

Applicable industry scope

EA402 913-402-000-012-A2-E040-F0-G000 is mainly applied in high-risk industrial fields where explosive gases or dust exist.

The petrochemical industry includes oil refineries, petrochemical plants, LNG receiving terminals, compressors, reactors and pumps on offshore platforms.

The pharmaceutical and fine chemical industries are respectively the synthesis and drying workshops where solvent vapors exist.

Energy is applied in coal mines (gas environments), gas turbine power plants, and biogas treatment plants.

Spraying and powder processing are concentrated in spray booths, flour mills, and aluminum powder/magnesium powder processing workshops.

Detailed comparison of advantages and disadvantages

Advantages

System-level security guarantees and compliance brought by Intrinsic Safety (Exi) certification

Legal and insurance compliance: In high-risk industries such as petrochemicals and coal mines, the use of non-EXI equipment is a serious illegal act, which may lead to projects failing safety acceptance, factories being ordered to suspend production, and even criminal liability in the event of an accident. The selection of this cable is a mandatory prerequisite for meeting major global safety regulations such as ATEX, IECEx, and OSHA.

The core value of eliminating the risk of ignition sources lies in the fact that even under the most severe fault conditions, the energy limited by the IQS 452 Exi preamplifier and transmitted through this cable is definitely insufficient to ignite the most flammable IIC class gases in the surrounding environment. This provides the last and most reliable physical barrier for personnel lives and factory assets worth hundreds of millions.

In some application scenarios, the use of Exi devices can downgrade areas that originally needed to be divided into Zone 1 to Zone 2, thereby allowing the use of lower-cost standard equipment and indirectly reducing the overall project cost.

The 4-meter standard length of EA402 913-402-000-012-A2-E040-F0-G000 offers outstanding engineering flexibility and economy

Four meters is the most frequently occurring distance between the probe and the installation position of the preamplifier in industrial sites. Choosing this standard length means:

No customization is required, avoiding the long delivery time and high NRE costs of non-standard products.

The simplification of the spare parts strategy enables factories to only stock a few standard lengths, which can cover over 90% of application scenarios, significantly reducing inventory costs and management complexity.

During emergency repairs, 4-meter cables, as universal spare parts, can almost always be found in the warehouse, minimizing the average repair time.

Disadvantage

The high fragility and strict installation constraints brought by no mechanical sheath

There is a high risk of physical damage. Although the FEP outer skin has excellent chemical properties, its tensile strength, wear resistance and cut resistance are extremely low. In industrial sites, cables may face the following threats:

EA402 913-402-000-012-A2-E040-F0-G000 was scratched by sharp edges of the bridge frame and burrs at the pipe penetration openings during the installation stage.

During operation, being crushed by moving equipment parts, injured by falling tools, or gnawed by rodents.

During the maintenance stage, it was accidentally stepped on by maintenance personnel or punctured with sharp tools. Any such injury may lead to:

The breakage of the shielding layer introduces strong electromagnetic interference, causing a sharp drop in the signal-to-noise ratio of the signal and a jump in the reading.

The exposure of the central conductor may cause a short circuit, trigger a preamplifier failure, and in extreme cases, even undermine the safety of the Exi circuit.

The cost and complexity brought by mandatory pipe threading requirements: To avoid the above risks, galvanized steel pipes must be run through the entire process. This brings about significant hidden costs.

The cost of materials such as steel pipes, elbows, junction boxes and sealed joints is much higher than that of the cables themselves.

Threading pipes is a time-consuming and highly technical task, especially in areas with limited space, where labor costs may account for over 70% of the total wiring cost.

The design complexity requires that the cable path be planned in the pipeline design stage, which increases the difficulty of multi-disciplinary coordination.
