It should be stated that a wire is an electrical conductor, while a cable is a group of
intertwined
wires and an integrated device. The term cable is used in the electrical field to
transmit electric
current. Proper wire and cable installation in closed and open spaces are extremely
important, and
ensuring a safe power supply is very important.
Types of cables in terms of application :
Today, in oil, gas, and petrochemical systems, military, defense, aerospace,
and missile industries,
medical and food industries, and any industry that requires control, and
measurement of flow
parameters, measurement of fluid volume and temperature, we will be directly
in touch with the
category of control and the instrumentation.
In instrumentation systems, to transfer the measured values, we need cables
that match the
measurements in control and instrumentation systems, and instrumentation
cables are an essential
part of measurement systems.
The appropriate type of instrumentation cable is selected according
to the kind of equipment, environmental conditions, and other electrical,
magnetic, and mechanical
parameters.
The low voltage cable is for voltages in the range of 300 to 3000 V. It is made with coatings of different materials and many variable conductor strings. Thus, according to the type of material used in the insulation and the number of conductor strands of these cables, which can be 2 or 5 strands, what passes through these cables is low voltage (LV) electricity, which in its simplest form, it comes to lighting and electrification of buildings.
Usually, among users, cables above 1 kV are defined as high voltage cables,
but according to
global standards, 32 kV and 63 kV cables are considered high voltage cables.
The structure of these cables is different according to their application. A
series of marks on it
indicates the specification of the high-voltage cable.
In general, cables always consist of two main parts: conductor and
insulation. The difference in
their price and types is due to their application, which means that their
kind of application causes
the material, shape, cross-sectional area, and the number of conductors and
insulators to differ.
The conductor used in the electric cable can be wire, strand, flexible, and
very flexible. Choosing
the electric cable's flexibility depends on the electrical conditions, the
required amount of
flexibility, the way the system is connected, and the installation
conditions.
Today, electric cables and wires play an important role in the fire safety of
buildings and facilities.
Excessive heating of wires and cables, arcing, short circuit, or electrical
fault can cause an accident.
Electrical insulation and coating compound will generally catch fire unless it
is fireproof or fire
resistant.
Cables significantly contribute to the spread of fire and heat release,
increased smoke
emission, increased carbon monoxide levels, and the production and release of
corrosive gases.
In order to create safety in the construction industry and the electricity industry, IRUS Energy Co. has provided environmentally friendly cables with increased safety during fire and accidents, and in this field, it has been able to meet part of the country's needs in accordance with the existing standards.
