6.35/11kV cable

19 Min Read
For a Type 3S 11kV feeder cable with 82–88 mm outer diameter (typically a 3x95mm² to 3x240mm² conductor), the appropriate Ex d cable gland must be sized to accommodate the cable's full outer diameter while maintaining the flange-threaded sealing design required by ATEX EN 60079-1 for Zone 1 explosive atmospheres. A typical selection for a 3x95mm² Type 3S cable would be an M100 or M105 flange-threaded gland rated for ATEX II 2G Ex d IIB T4, with a compressive sealing ring (typically 2 mm thick polyurethane or equivalent elastomer) that creates a pressure-tight barrier against explosive gas ingress, and a separate earthing screw or braided conductor that bonds the cable's steel wire armor directly to the enclosure's earth continuity. This is not simply a matter of finding any cable gland that fits the cable diameter—it is a critical safety component that must be certified, specified, and installed with precision.

Ex d Gland Matching: Terminating Type 3S 11kV SWA Armor in Hazardous Zone 1

For a Type 3S 11kV feeder cable with 82–88 mm outer diameter (typically a 3x95mm² to 3x240mm² conductor), the appropriate Ex d cable gland must be sized to accommodate the cable’s full outer diameter while maintaining the flange-threaded sealing design required by ATEX EN 60079-1 for Zone 1 explosive atmospheres. A typical selection for a 3x95mm² Type 3S cable would be an M100 or M105 flange-threaded gland rated for ATEX II 2G Ex d IIB T4, with a compressive sealing ring (typically 2 mm thick polyurethane or equivalent elastomer) that creates a pressure-tight barrier against explosive gas ingress, and a separate earthing screw or braided conductor that bonds the cable’s steel wire armor directly to the enclosure’s earth continuity.

The Type 2S 11kV 3x95mm² cable has a base ampacity of 285 amperes when installed in free air at 40°C ambient temperature. However, in a typical underground mine substation where three or more feeder cables are installed side-by-side on a cable ladder, the practical usable current is reduced to approximately 228 amperes through application of temperature and grouping derating factors. This 228 A figure is the number that should govern your design calculations and equipment sizing for the substation feeder. Type 2S 11kV 3x95mm² 电缆在 40°C 环境温度的自由空气中安装时，其基础载流量为 285 安培。但在地下矿山变电站中，三根或更多馈电电缆并排安装在电缆桥架上的典型情况下，通过应用温度和编组降额系数，实际可用电流减少至约 228 安培。这个 228 A 的数字应该管理您的设计计算和变电站馈电的设备选型。

The nominal outer diameter (OD) of an AS/NZS 1972 Type 2S 11kV 3x185mm² feeder cable is 76.0 to 80.0 millimeters (3.0 to 3.15 inches). The typical design center for Feichun's Type 2S 3x185mm² product is approximately 78.6 mm. This measurement is taken across the outermost surface of the flame-retardant PVC sheath, which forms the final protective layer after the galvanized steel wire armour (SWA) and inner insulation geometry. 澳标 AS/NZS 1972 Type 2S 11kV 3x185mm² 馈电电缆的标称外径为 76.0 至 80.0 毫米（3.0 至 3.15 英寸）。 Feichun Type 2S 3x185mm² 产品的典型设计中心约为 78.6 mm。该测量是在钢丝铠装 (SWA) 和内层绝缘几何结构之后，在阻燃 PVC 外护套的最外表面进行的。 This 76–80 mm range is not arbitrary—it represents the accumulated thicknesses of multiple cable components layered concentrically around the three power conductors. To understand where this dimension comes from, an electrical engineer planning a mine installation must understand the contribution of each layer.

The Single Most Important Cable Design Decision in Underground Coal Mining: Whether the cable employs collective screening (Type 2) or individual phase screening (Type 2S). This single engineering choice directly determines whether a mechanical cable failure will result in a phase-to-earth fault (detected and stopped in milliseconds) or a phase-to-phase fault with thousands of amperes of arc current (igniting methane explosions).

Type 2 vs Type 2S: Why the “S” (Individual Screen) is Mandatory for 11kV Underground Coal Mines

The international nature of power infrastructure means that MV cables are specified using various national nomenclatures and standards. While the German DIN VDE nomenclature (such as N2XSY, NA2XSH) has become widely recognized across Europe, British Standards (BS6622, BS7835, BS7870), French (NF C 33-226), Spanish (RHZ1), Portuguese (XHIOE, LXHIOV), and other national specifications remain essential for projects in their respective regions.

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.

What is 6.35/11kV Cable?

6.35/11kV voltage is commonly associated with armoured cable – the aluminium wire armour (AWA) for single core cables and steel wire armour (SWA) for multicore cables providing robust mechanical protection that makes 11kV cables suitable for direct burial in the ground. These armoured MV mains power cables are more commonly supplied with copper conductors but they are also available with aluminium conductors upon request to the same standard.
