This family of barrier cable glands includes four models: BXN, BXC, BXA and BXM; all of which may be resin coated with a two component epoxy resin. The solid state of the resin makes it possible to assemble the cable glands even in a horizontal position; as sometimes happens during phases of maintenance on the systems. These cable glands may be used for the simultaneous passage of additional cables, limiting the use of the pre-sealed nipples. The internal container for the resin is removable allowing for the inspection of the cable glands after the resin treatment.
Cable glands are suitable for sealing unarmoured cables with single core or multiple cores.
Inside the container, a single cable or multiple cables may pass through, sometimes avoiding the use of pre-resinated nipples.
02 No loose parts
Some parts of the cable gland are integral with each other by means of O-ring seals which in addition to guaranteeing the degree of IP protection also avoid accidental loss of the parts.
Possibility of choosing between execution of the backnut for use with a conduit with a tapered end or to a flexible conduit.
The internal container for the integrated resin in the body of the cable gland may be removed, making it possible to inspect the cable gland once it has received the resin treatment.
Fewer parts reduces the chance of losing or incorrectly assembling the same within the cable gland.
06 Easy assembly
Internal silicone O-ring which prevents water or moisture from getting in via the threaded connection between the body and the intermediate and the resulting corrosion of the armour/cable shield.
Preparation of epoxy resin - steps 01 to 04
When using the compound, be sure to wear the gloves provided with the resin.
The epoxy resin is provided in a package with two separate parts. These must be mixed in a ratio of 1:1 until the compound is a single colour and without streaks.
The best solution for mixing the two parts is by rolling and bending the components several times together. Once mixed, the resin must be used within 30 minutes.
Over time it will begin to harden. The compound should not be stored at a temperature below 20°C before being mixed. At lower temperatures, it will
becomes difficult to mix. 3 to 4 hours are necessary at a temperature of between 20°C to 30°C so that the compound solidifies. They have to spend 12 to 24 hours at a temperature of between 20°C and 30°C until the compound reaches an optimal state.
If the compound comes in contact with one’s skin, it must be removed with a detergent and in no case allowed to harden.
Mix only enough compound to assemble one cable gland at a time.
The compound may be adversely affected by certain solvent fumes. If these fumes are present in the vicinity of the cable glands in service, specific precautions may be necessary. The compound polymerizes to a Shore hardness of 85. The compound, when completely set, is suitable to use at a range of service temperatures from -60°C to +130°C.
Note: Consider that the setting time may be longer when the room temperature is below 20°C.
Application of the epoxy resin - steps 05 to 08
Prepare a resin cylinder to the required size 05.
Place it inside the cables as shown in figure 06.
Tighten the cables until they are in the resin and if necessary, add more resin to the outside so as to get a resin cylinder homogeneous with the cables inside 07.
Move together the container and the upper ring; be sure to get rid of any excess
resin. Then insert the container into the gland body and tighten the backnut to the body. Let it sit long enough for the resin to harden. Once the resin has polymerised, it will be possible to inspect the container and check the result 08.
