GEXOL 37-102 Armored & Sheathed (BS): Installation Guide for Explosion Proof Zone 1

The GEXOL 37-102 cable family, manufactured by Nexans AmerCable （由Nexans AmerCable制造）, represents a sophisticated engineering solution that bridges North American marine cable standards with international protection requirements for hazardous location installations. Understanding the specific engineering principles that govern the “Armored & Sheathed (BS)” configuration is essential for electrical engineers and procurement specialists tasked with specifying cables for Zone 1 explosion-proof environments （防爆 1 区环境）, particularly in offshore drilling platforms, subsea installations, and petrochemical facilities.

Armoured cables, commonly referred to as SWA (Steel Wire Armoured) or AWA (Aluminium Wire Armoured) cables, are robust power cables designed with metallic armour protection for demanding installation environments. The armour provides mechanical protection where physical stress could damage the cable, such as direct burial underground, outdoor installations, or industrial environments. These cables are manufactured in accordance with British, European, and International standards including BS 5467, BS 6724, BS 6622, BS 7835, and IEC 60502.

SANS 1507 standard, published by the South African Bureau of Standards (SABS), specifies requirements for electrical cables with extruded solid dielectric insulation designed for fixed installation. This comprehensive standard covers cables with voltage ratings from 300/500V to 1.9/3.3kV, encompassing wiring cables, distribution cables, and service cables used throughout South Africa and many other African nations.

Whilst low voltage generally refers to cables under 1kV voltage, the 1.9/3.3kV cables are often classified within this banding too. These cables represent the upper boundary of the "extended low voltage" classification and are primarily manufactured in accordance with British Standards BS5467 and BS6724. The 1.9/3.3kV rating indicates cables designed for systems where the phase-to-earth voltage is 1.9kV and phase-to-phase voltage is 3.3kV, with a maximum system voltage (Um) of 3.6kV.

BS6724 is a British Standard specification for thermosetting insulated, armoured cables with rated voltages of 600/1000V and 1900/3300V, specifically designed to have low emission of smoke and corrosive gases when affected by fire. This standard is widely adopted in the UK and internationally for applications where fire safety is critical.
