Products Description

Offshore instrumentation cables carry sensor and control signals for offshore platforms and marine installations.

Exposed to salt spray, high humidity, constant vibration and mechanical stress out at sea. Fine-stranded tinned copper handles flexing from platform movement. Optimized low-capacitance design keeps 4-20mA sensor readings stable. Shielding cuts electrical crosstalk and motor noise. Special offshore-grade sheath fights salt-water corrosion, oil and chemical splashes. Used for monitoring systems, field sensors and control loops on offshore facilities.

Each lot completes full electrical verification before leaving factory

FAQs

Q1: What causes most instrumentation cable failures offshore?

A: Most issues come from platform vibration and salt mist eating the sheath. Our offshore-grade cable handles these real-world conditions, helping reduce unplanned downtime and frequent replacements.

Q2: Can nearby power circuits mess up our 4-20mA sensor signals?

A: Pair-shield design helps block outside electrical noise. Low-capacitance build keeps sensor readings stable, even over long cable runs across the platform.

Q3: Do you offer various cable versions for our offshore tender project?

A: We supply SWA armour, LSZH and flame-retardant options. Every batch is electrically tested before shipment to fit offshore site requirements.
