FAQ.

What medium-voltage equipment does a refinery use?

Refineries and petrochemical plants use medium-voltage switchgear, distribution transformers, cable terminations and splices, and grounding to carry power across the site to process and utility loads.

The five equipment categories on this page cover that scope. Each links to its full category page with the manufacturers Hawk carries for it.

How do hazardous-location requirements affect equipment selection?

Parts of a refinery are classified hazardous (NEC Class I) locations. Equipment placement, enclosure type, and area classification are governed by NFPA 70 Article 500, API recommended practices, and IEC 60079.

Area classification is confirmed for each installation by the customer's engineer. Hawk supplies equipment to that specification and does not certify hazardous-location compliance.

What standards apply to refinery electrical work?

Refinery and petrochemical electrical systems reference API RP 540 and API RP 14F, IEEE 1349 for motor application in hazardous locations, NFPA 70 Article 500, and the IEC 60079 series.

API RP 540 covers electrical installations in petroleum processing plants; API RP 14F covers offshore facility electrical systems including Class I Division 1 and 2 locations.

Does Hawk publish pricing for refinery projects?

No. Equipment is configured and priced per project.

Medium-voltage equipment for refineries and petrochemical facilities.

Refineries, chemical plants, and LNG and midstream facilities run medium-voltage distribution through environments where parts of the site are classified hazardous (NEC Class I) locations. Equipment selection is shaped by area classification, corrosion, and the API and IEC standards that govern electrical systems in petroleum and chemical facilities — API RP 540, API RP 14F, IEEE 1349, NFPA 70 Article 500, and the IEC 60079 series. Area classification governs equipment placement and enclosure type and is confirmed for each installation by the project's engineer.

The medium-voltage scope Hawk MV Supply sources for these facilities spans the five categories on this page: switchgear, transformers, cable terminations and splices, and grounding — from the five manufacturers listed above. Hawk supplies equipment to specification and does not certify hazardous-location compliance.
