What governing standard and construction define 52A SERIES (52A Series 600 V Heavy-Duty Underwater & Nuclear Lighting Cable)?

52A SERIES (52A Series 600 V Heavy-Duty Underwater & Nuclear Lighting Cable) is manufactured in accordance with NAVSEA S9320-AM-PRO-020 / CERN 10⁶ Gy Nuclear Standard for 600 V service over -40 °C to +90 °C. Its 4-layer construction comprises extra-flexible bare copper (3×16/14/12 awg), 90 °c epdm / styrene rubber insulation and nuclear-grade cspe / heavy-duty pcp jacket.

What is the minimum bending radius and operating temperature range for 52A SERIES?

The minimum bending radius for 52A SERIES is 6 × OD across its continuous operating temperature range of -40 °C to +90 °C, ensuring mechanical and dielectric reliability in subsea, marine and submersible service.

How are the concentric layers of 52A SERIES arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Extra-Flexible Bare Copper (3×16/14/12 AWG) — Soft-drawn annealed bare copper rope/bunch stranding (41×#30 or 65×#34/30); (02) 90 °C EPDM / Styrene Rubber Insulation — 600 V high-dielectric radiation-tolerant rubber insulation (Black, White & Green); (03) Round Mold-Ready Core Lay-Up — Three cores cabled round for NAVSEA S9320-AM-PRO-020 watertight overmolding; (04) Nuclear-Grade CSPE / Heavy-Duty PCP Jacket — Yellow CSPE nuclear-grade jacket (52A-013/033/023) or Black Polychloroprene (52A-006/009/012).

What factory test certificates are supplied with 52A SERIES?

Every production drum of 52A SERIES undergoes routine conductor resistance/continuity, high-voltage dielectric and dimensional testing per NAVSEA S9320-AM-PRO-020 / CERN 10⁶ Gy Nuclear Standard, and is delivered with an EN 10204 3.1 factory test certificate.
