Innovative cable jointing for reliable cable connections

HellermannTyton offers many other solutions for electrical insulation and moisture protection in the low-voltage range. One example is the transparent, saltwater-resistant and removable 2-component gel RELICON KH 67. The 2-component gel RELICON KH 100 has similar properties and can be easily applied with a standard cartridge gun.

You can find more information about our gels and gel joints here on a separate page.

The cast resin and hardener are in a transparent two-chamber bag. When the bag is kneaded, the inner seam breaks and the two components can mix. During mixing, the mass changes colour. The transparent bag makes it possible to see when the mass is homogeneously mixed.

The advantage of the integrated filling funnel is the safe and clean filling of the joint shell without you coming into contact with the cast resin.

Mechanical protection is intended to protect the cable from physical influences such as impact (due to excavation work), movement, abrasion, tensile forces, traffic vibration (sub-standard work by construction workers, vehicle movement rattles the installation), vibration and pressure (e.g. due to earth masses, water or weight of the cable).

Mechanical protection often also provides protection against thermal stress.

HellermannTyton cast resin joints are tested according to EN 50393, which corresponds to DIN VDE 0278-393. EN 50393 includes the following test procedures:

1. alternating voltage test in air (4Kv for 1 minute)
2. insulation resistance test in air
3. impact resistance at ambient temperature
4. alternating voltage test in 1m water depth (4Kv for 1 minute)
5. insulation resistance test in 1m water depth
6. load cycle test in air (63 cycles x 8 hours = 504 hours)
7. load cycle test in water (63 cycles x 8 hours = 504 hours in 1m water depth)
8. alternating voltage test in 1m water depth (4Kv for 1 minute)
9. insulation resistance test in 1m water depth
10. examination

The degrees of protection are indicated by an abbreviation code consisting of the  letters IP ("International Protection") and two numbers for the degree of protection. The first number represents the protection against contact and penetration of foreign bodies and dust, while the second number represents the protection against water ingress. Our cast resins have protection class IP68, which means the following:

6 = protection against dust ingress and physical contact

8 = Protection against permanent immersion

HellermannTyton cast resin sleeves automatically meet the requirements of protection class IP68 and the higher requirements of EN 50393 due to their design. For this reason, a separate test is not necessary, which means that we do not publish the IP68 protection class.

All HellermannTyton cast resins are labelled SVHC-free. This means that the cast resins do not contain hazardous substances and can be processed as such. However, to mitigate any risk of skin contact, we supply you with protective gloves. We advise you to wear them during the complete mixing and filling process. Should you nevertheless come into contact with a cast resin, wash the area under running water or use our Reliclean cloths.

The shelf life of our cast resins varies. In general, the following storage times apply when stored properly in the original packaging at +5 °C to +40 °C:

• PUR 33: up to 48 months

As soon as the two cast resin components are homogeneously mixed and have reacted, the cured cast resin is harmless to the environment and is not hazardous waste. Therefore, old cast resin joints and cured cast resin residues can be disposed of in normal household waste. Please note that cast resins must be processed and cured according to the packaging instructions before disposal. For larger quantities, contact the respective disposal company beforehand to ensure proper disposal, as these are regulated differently in some regions.

• Sub-zero temperatures: Cast resins can also be used at low temperatures as long as the resin is warmed to at least 10 °C or higher before mixing. Higher temperatures will result in a faster curing time.
• Under water: Cast resin cannot be poured under water. However, the cast resin hardens directly after filling the joint, even under water without foaming. Accordingly, the cast resin joint can be placed under water directly after filling, even if the cast resin has not yet fully hardened. Our cast resins are hydrophobic and especially for this application requirement.
