Description
Key Applications
-
Corrosion Protection: Large M40/42mm brass glands have a wide surface area prone to oxidation. The shroud prevents “crevice corrosion” in the threads and clamping zones.
-
Earthing Security: It protects the Earth Tag (Banjo) and the armor clamping ring from moisture. This is vital because, at these power levels, a corroded earth connection can lead to dangerous fault conditions.
-
Environmental Sealing: It diverts water, oil, and dust away from the entry point of the distribution board or motor terminal box, maintaining an IP66 rating.
Technical Specifications
-
Compatibility: Fits M40 x 1.5 metric glands, 1 ½” / 1 ¾” ET industrial glands, and PG36 glands.
-
Material Options:
-
Standard PVC (Black): UV-stabilized for outdoor industrial use.1
-
LSF/LSOH (Low Smoke and Fume): Usually grey; mandatory for indoor public infrastructure (stations, hospitals, tunnels).
-
-
Temperature Range: -60°C to +90°C.
-
Internal Diameter (Bell): Approximately 55mm–60mm to allow for the large hexagonal nut of an M40 gland.
Professional Installation Tips
Handling a shroud of this size requires specific techniques due to the thickness of the PVC.
| Step | Technique | Why? |
| 1. Heat Treatment | Soak the shroud in boiling water for 3–5 mins. | At 42mm, the PVC is very rigid. Heating it makes it elastic enough to stretch over the gland. |
| 2. Precise Trimming | Cut the “tail” in small increments. | You want the tail to be roughly 3-4mm smaller than the cable’s outer diameter for a true waterproof tension fit. |
| 3. Lubrication | Apply a small amount of silicone grease to the cable. | This allows the heavy PVC shroud to slide down the cable without snagging. |
| 4. Alignment | Ensure the “bell” end covers the Earth Tag. | If the tag is left exposed, it will rust quickly, compromising the safety of the circuit. |
