Barrier Cable glands for unarmoured and wire armoured or braided, tape armoured, lead sheathed cables.
“B series” cable glands offer a wide variety of products, suitable to meet all customer needs.
The cable glands are available in a standard version or with a male or female threaded backnut, the trumpet backnut perfect for mobile poses in which potential damages must be limited caused by repeated bending of the outgoing cable of the cable gland. Suitable versions for cables coated with lead sheathing are also available.
The container positioned inside the body of the cable gland aids the gathering of the epoxy resin for the resin treatment as required in some applications of the EN/IEC 60079-14 standard.
Two kinds of resin are available: a liquid and a solid, which may be used according to the needs of the client.
The material of the cable glands may be natural brass or nickel-plated brass, stainless steel AISI 316L and aluminium.
The interior washer may be EPDM or silicone; to be selected according to the operating ambient temperature, like the seal are available in nylon, silicone or PTFE or O-Rings available in EPDM or silicone.
The wide variety of available threads allows the user to choose the most suitable for their needs; this will limit the use of threaded adaptors to reduce the overall dimensions and application costs.
The rubber pad thanks to its particular design, clamps the external diameter of the cable for the entire height of the passage hole, ensuring the highest tensile seal and protecting the cable from any possible damage caused by different rubber pads, with its form which tightens the cable in only one point. This feature means that these cable glands do not require any additional clamping to the cable up to size 50.
Possibility to choose between implementation of the body with OR or flat gasket, according to their needs and following material couplings in compliance with operating temperatures.
Container for resin integrated into the cable gland body and easily inspected.
Reduced number of components, which reduces the possibility of loosing some parts or incorrect assembly..
External rubber pad which locks the outer sheath of the cable, providing protection against water and moisture.
ONLY FOR ARMOURED CABLE
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.
