This type of installations is part of the basis of any hotel, residential or singular project, and this is the main reason why ESTEL has made this branch one of our main axes.
Throughout our history we have specialized in different fields ranging from low voltage to the most innovative power generation systems on the market. We are able to fully develop electrical installations in any project and in any corner of the world.
When we talk about the hotel sector, electrical installations require extra experience in terms of regulations and design because we are talking about installations with maximum scope and requirements, together with the fact that we are talking about an industry where millions of customers and their families spend the year and here any detail, no matter how small, is very important.
At ESTEL, when we focus on the design of electrical installations, we are at the top of the list of leading companies in the hotel sector worldwide. This is the result of our own demand where at the project level we not only think about the correct sizing and the customer’s life experience with these facilities, but we also think and design the facilities from the sensitivity that has been generated in recent years both by the consumer and by us, in terms of sustainability.
This is the reason why the projects that come out of our organization, the efficiency is calculated down to the last detail both thinking about the consumer and the property, which in addition to helping the environment with a well dimensioned installation, will see how their costs are reduced to a minimum by significantly improving the efficiency of the system
Within the electrical installations there are different types of electrical conductors with variants according to the material, the type of insulation and their use.
First, we can divide them according to their use, which can be low, medium or high voltage. This will depend on the voltage range.
On the other hand, the type of material in conductors can be copper or aluminium, where the difference is that aluminium is more economical, and is used for installations with medium and high voltages.
As for the type of insulation we can differentiate: 750V, 0.6/1kV, 12/20, 18/30kV. These can have a PVC, XPLE or RV-V FOC covering.
These elements are essential to ensure the proper functioning of electrical systems. They include circuit breakers, which protect the electrical installation against overloads or short circuits. It depends on the amperage and the curve.
On the other hand, differential switches are responsible for interrupting the current when a fault, leakage or shunt is detected. Their type depends on sensitivity and amperage.
The main function of fuses is to protect the circuit against overvoltage. Their type depends on the amperage.
Previously described, the electrical panels protect the electrical installation of a house, hotel and any infrastructure.
Electrical installations must comply with demanding regulations and standards that vary from country to country. These regulate aspects such as safety, quality of materials and correct execution of installations.
Some examples of low voltage regulations:
Example of some high voltage rules:
Some standards and regulations on medium voltage:
There are 5 basic rules to follow when performing electrical work:
The authorized electrical installer is the one who certifies that the electrical installation complies with the regulations and conforms to the legal requirements.
At ESTEL we have a business line in charge of carrying out revisions and maintenance of the installations, EstelSat, which offers 24/7 service.
Performing periodic reviews of electrical installations can prevent future failures and outages, reducing the additional cost that this entails.
The most common problem that usually arises in electrical installations is the short circuit of fuses or that some protection element has been overloaded.
To achieve energy efficiency, one of the most important things is to design and plan how and with what materials the electrical installation will be made. This will increase the energy efficiency and durability of the components. It is also very important the installation of efficient technological systems, to reduce pollution and energy optimization. An example can be the installation of appliances with high performance and low consumption. Implementing control and automation systems also helps energy efficiency, since we will have the possibility of turning on the devices when necessary, being sustainable and achieving energy savings.
An important point in the field of electrical installations is the electrical supply in the hotel sector. From ESTEL we have a supply service generated from the needs of our customers, where we can install co or trigeneration plants near their facilities to save them a lot of money by not depending on external substations that are often far away from their hotels. At the same time, we improve the efficiency of the whole by making much better use of the residual energies of the electricity production, which has a direct impact on the cost reduction.
Home automation is the set of intelligent elements for both residential and hotels, industry, hospitals, etc. that allow us to automate the control and operation of some elements of the installation. There is the possibility of automating from the opening of blinds to the control of the electrical consumption of a hotel room.
After 28 year and projects done in 20 countries, the 50% of our turnover comes to projects carried out in foreign markets. We have several international delegations in México, República Dominicana, Jamaica, Puerto Rico, Costa Rica, USA, Qatar, Perú, Colombia and Argelia.
