Types of cables
An electric cable has the purpose of transporting electrical energy from one point to another. Depending on their final application, cables can have different configurations, always basing their design on national and international regulations.
Low voltage cables (up to 750 V): in a variety of applications, and with thermoplastic and thermoset coatings. They are designed and built according to harmonized standards.
Low Voltage cables (up to 1,000 V): (also called (0,6/1 kV) The cables in this section are used for industrial power installations in various fields (general industry, public installations, infrastructures, etc.). They are designed according to international standards (UNE, IEC, BS, UL).
Medium Voltage cables: from 1 kV to 36 kV. They are used to distribute electricity from electrical substations to transformer stations.
High Voltage cables: from 36 kV. They are used to transport electricity from the generating plants to the electrical substations.
Types of electric cable by their use
Low voltage cables
Cables for electric panels
Flexible cables for wiring electric cabinets. These electric cables are especially suitable for domestic use, for installation in public places and for internal wiring of electrical cabinets, switch boxes and small electrical appliances.
Power cables
Energy cables for industrial facilities and public places. It is common to find power cable in applications for power transmission in all types of low voltage connections, for industrial use and for variable frequency drive (VFD).
Armoured cables
Cables with aluminium or steel reinforcement for installations with risk of mechanical aggression. It is also common to find armoured cables in places where rodents are present, as well as in installations in premises with a risk of fire and explosion (ATEX).
Rubber cables
The use of extra flexible rubber cable is very varied. We can find rubber cables in fixed industrial installations as well as in mobile service. Welding cables should have a rubber sheath, which allows high currents to be transmitted between the welding generator and the electrode.
Halogen-free cables
High Security Halogen Free (LSZH) Cables with low smoke and corrosive gas emission in case of fire are suitable for use in wiring of electrical panels and public places, installations of all kinds in public places, individual derivations, emergency circuits, public distribution networks and also for mobile service.
Fire resistant cables
These cables are specially designed to transmit electrical energy in the extreme conditions that occur during a prolonged fire, guaranteeing supply to emergency equipment such as signalling, smoke extractors, acoustic alarms, water pumps, etc. Their use is recommended in emergency circuits in places with public concurrence.
Control cables
Control cable for fixed or mobile installations should be extremely flexible, as they are mainly designed for small household appliances, for the interconnection of machine parts used for manufacturing, for signalling and control systems, for the connection of motors or frequency converters, for signal transmission where the voltage induced by an external electromagnetic field may affect the transmitted signal or for power supply connections to avoid generating electromagnetic fields.
Instrumentation cables
These are flexible and shielded cables for the transmission of signals between equipment in industrial installations. Especially suitable for optimum data transmission in environments with a high level of electromagnetic interference.
Solar cables
These cables are particularly suitable for connecting photovoltaic panels, and from the panels to the DC to AC inverter. Thanks to the design of their materials and their cover, which is especially resistant to solar radiation and extreme temperatures, they can be installed outdoors with full guarantees.
Special cables
There is a wide variety of electric cables for special installations such as: temporary light garland installations at trade fairs; connections for overhead cranes, hoists and lifts; applications in submerged pumps and drinking water areas such as aquariums, purification systems, drinking water fountains or in swimming pools for lighting, purification and cleaning systems.
PVC Cables or PUR Cables: How to Choose the Right Cable
Cables are an essential part of any industrial application. It is important to make sure that you choose the appropriate cable material for the environment, especially where chemical cleaning solutions, cutting fluids, and other caustic liquids are present. The two main types of cables used in industrial applications are either PVC or PUR, and they are each suited to different types of environments. This article describes the difference between PVC and PUR cables and when to use each type of cable.
PVC Cables and When to Use Them
PVC cable is Polyvinyl Chloride (PVC) cables that is sheathed and insulated. PVC cables are an excellent choice for most chemical washdown applications in the food industry and beverage industry. They have good-to-excellent resistance to common cleaning solvents including, but not limited to:
