Low Voltage

1- What are the differences between the various gel fillers in the Etelec Italia range?

MPGel is an extremely fast cross-linking gel that allows you to encapsulate, fill and seal a tesion part or electronic board very quickly.
Crystalgel is a transparent filler gel that allows the isolated components to be seen.
Replaygel is a repositionable filler gel ideal for isolating connections and components that need to be accessed again after sealing without having to use a new product.
ONEGEL single-component filler gel in silicone gun cartridges ideal for filling and insulating junction boxes placed in ceilings, walls or hard-to-reach spaces.

2- What advantages are gained from using gel compared with traditional insulation methods?

Gel technology allows multiple advantages over more traditional methods such as resins, while still providing the same performance in terms of electrical insulation. The main advantages are highlighted by the nontoxic characteristics, safety during installation, and reusability of the product following the first opening.

3- What gel should I pour inside the SHARK joints?

SHARK joints are pre-filled with insulating gel so they are immediately usable!

4- What is the difference between SHARK joints and solutions such as SHELLBOX or SHELLBOX FLAT models?

SHARK models are splices in that they meet all the necessary characteristics according to European standard EN50393. As such they can be used for in-line joining of two or more cables, interrupted or not. Compliance with this standard allows these junctions to be used in manholes, underground areas and in air.
The SHELLBOX series, on the other hand, is a series of connection devices ideal for protecting live parts inside enclosures such as junction boxes or false ceilings.

5- In what case is it advisable to use the LedJoy model?

The Ledjoy is an ideal connection device for all types of connections to be made even in confined spaces where moisture is present. Designed to be quick and easy to install without the use of tools. Perfect for domestic and civil lighting installations, civil and industrial automation (automatic bars, gates and the like) and video surveillance systems.

6- I need to make a permanent immersion splice, what can I use?

Our range of Seal Joint heat-shrinkable joints are perfect for this type of installation. The thermofusible sealant contained on the inner wall of the outer sheath, when melted, protects live parts from moisture and capillary water. Alternatively, you can use the soldio Submarine series of final-state cast resin joints.

7- What is the fastest low-voltage splicing system?

The choice of a joining system always depends on the type of application, but especially on the installation conditions. In general, the gel solution is preferred over cast resin or heat-shrink resin because : For cable tray and cable duct installations, gel technology with pre-filled shells - SHARK® range - is certainly the fastest solution. For aerial installations, it is difficult to use cast resin technology because a support point is needed to be able to pour the resin without allowing it to flow out of the shell. Heat-shrinking technology is also difficult because the operation of heating with a torch flame or heat-blower can tire the operator in the long run, especially if the operator does not have to work in a comfortable position. For underground installations, heat-shrink technology is difficult because the heating operation with blowtorch flame or heat-blower in the long run can tire the operator, especially if the operator should not work in a comfortable position. Cast resin technology also involves difficulties in execution because in the absence of a foothold to be able to cast the resin, there is a risk of it leaking out of the shell.

Medium Voltage

1- In the package of Medium Voltage termination kits, are there instructions for aluminum cable as well?

All kits, both heat shrinkable and self-shrinkable, can be installed on cables with either copper or aluminum conductors, without having to make any distinction or special installation attention, except for cable types ARE4H5E(X) and ARP1H5E(X) , for which we have dedicated termination kits in the catalog, i.e., all those that have code ending for H5.

2- Difference between self-shrinking and heat-shrinking technology?

The main difference between autoreshrink and heat-shrink technology is found in the installation. The conduits found in heat-shrink kits require a heat source to be applied, unlike autoreshrink bodies that are installed by removing the supporting spiral.
As far as electrical insulation is concerned, the technologies are entirely equivalent.

3- What are disconnectable terminals?

Disconnectable technology allows terminations to be connected and disconnected from the electrical equipment to which they are applied by through-insulators.
There are various classes of disconnectable terminations depending on the type of insulators to which they are applied and the rated current they must handle.

4- What information is needed to be able to choose the correct termination model?

For self-shrinking or heat-shrinking terminals:
1) The insulation voltage of the cable (e.g. 12/20kV; 18/30 kV)
2) The conductor cross-section of the cable (e.g. 95 mm2)
3) The type of shielding and/or armor (e.g., copper wire or aluminum tube)
For disconnectable terminals, in addition to the above:
4) The type of through-insulator (outer or inner cone)
5) The diameter on the primary insulator
6) The rated operating current (e.g., 250 A; 400 A; 630 A; 800 A; 1250 A)

5- What information is needed to be able to choose the correct joint model?

1) The insulation voltage of the cable (e.g. 12/20kV; 18/30 kV)
2) The cross-sectional area of the cable conductor (e.g. 95 mm2)
3) The type of shielding and/or armor (e.g., copper wire or aluminum tube)

2- What is the difference between constant power heating cables and self-regulating power?

Constant-power heating cables provide constant power per linear meter (W/m) regardless of contact or external conditions. The matrix of which self-regulating power heating cables are made, on the other hand, allows delivery of the power strictly necessary to achieve thermal equilibrium, providing considerable energy savings when it is not necessary to use all the deliverable power of the cable.
