Fully protected bare electrical connections
A somewhat unique and novel range of sealing products that enable manufacturers, installers and those in maintenance to upgrade bare cable connections into waterproof types is now available from Switchtec. Manufactured by Arnocanali, the product range embraces gels and sealing pastes that can render a simple, unsealed junction box to become IP68 ingress rated.
The need to interconnect cables is a very common occurrence during an installation. Such interconnections are generally made by uniting two or more cables within a terminal block or connector. To protect the connection the connector is often fitted inside an enclosure. However, if this installation is outdoors, requires submersing or burying, is at risk of extreme liquid exposure, or exposed to extreme temperatures, then the ingress of water or condensation build-up may become an issue for the connection by creating an electrical fault. To prevent or to cure an ongoing issue, the use of Arnocanali’s sealing gels or pastes provides a solution, fully insulating the connection.
Aimed at OEMs, contractors, installers, and distributors, the Arnocanali sealing products can be used for enclosure sealing, waterproofing, and insulating electrical installations.
For versatility there are three types of sealing solution, the most popular is the bi-component gel. This is supplied as a two part liquid that when mixed becomes a semi rigid, translucent gel. The second is the bi-component rubber, which has the same characteristics as the gel but is opaque. Thirdly, the sealing paste product is supplied ready mixed and has an extremely high viscosity that can be moulded and re-used as it does not cure.When applied to a suitable enclosure, Arnocanali sealing gels and pastes ensure an IP68 level of ingress protection. The gels have a fast cure time of 15 minutes even at low temperatures. They are low viscosity, non-toxic, and feature good transparency and no shelf life. They have high dielectric strengths of 20kV per mm and are suitable for installations up to 1kV.
The gels can replace all types of resins, with the added benefit of being able to remove the compound without damaging the enclosure or connections. The gel comprises of a cross linking polymer, supplied in two parts (bottles or bag). The mixed gel has a very low viscosity, and when poured surrounds and envelopes any type of material, insulating any electrical connection, and curing within 15 minutes. The resulting material is completely non-toxic, will not stress materials it comes into contact with, and once removed can be disposed of safely.
As well as being available direct from Switchtec, Arnocanali gels and pastes are available in point of sale promotional packaging for trade counter display.
