Today's modern buildings are equipped with complex electrical systems. The flawless operation of lighting, heating, cooling, communication, security and many other systems depends on correctly selected and safely installed installation cables. Plumbing cables are vital components of buildings that carry and distribute electrical energy. As Ülkü Kablo, we will explain what installation cables are, their types, features, standards and what should be considered in their selection.
The Importance of Installation Cables
Installation cables ensure the safe and efficient transmission of electrical energy from the source (electrical panel) to the points of consumption (sockets, lamps, appliances, etc.). Improperly selected or improperly laid cables can lead to serious problems such as fire hazard, risk of electric shock, appliance failures, and energy losses. Therefore, the correct selection and professional installation of plumbing cables is of great importance.
Types of Installation Cables
The main types of cables used in installations are:
- NYA Cables (NV Cables): They are single-core, PVC insulated cables. They are often used indoors, in pipes or under plaster. They are frequently preferred in lighting installations and socket connections. Thanks to their flexible structure, they are easy to install.
- NYM Cables: They are multi-core, PVC insulated and PVC sheathed cables. They can be used both indoors and outdoors (provided that they are not buried directly in the ground). They are more durable and safer. They are used in fixed installations of residential and commercial buildings, lighting and power distribution systems.
- NYY Cables (YVV Cables): They are multi-core, PVC insulated and PVC sheathed cables. They are similar to NYM cables but have a thicker outer sheath. In this way, they are more resistant to mechanical stresses. They are used underground, in cable ducts and in outdoor networks.
- NYMHY Cables: They are very thin wired, PVC insulated and PVC sheathed cables. They are especially used in mobile device connections and applications that require flexibility. They are common as connecting cables for household appliances, lamps and similar devices.
- Halogen Free Cables (NHMH, N2XH etc.): These are special cables that do not emit toxic gases in case of fire. They are preferred in buildings with high human density (hospitals, schools, shopping malls, etc.) and in places where fire safety is critical.
- Antigron Cables (FE180 / E30 / E90): These are special cables that are resistant to fire and maintain their function for a certain period of time. They are used in systems such as fire alarm systems, emergency lighting and fire pumps.
Features of Installation Cables
Here are some important features to consider when choosing and using plumbing cables:
- Conductor Material: Copper is usually used. Copper minimizes energy losses thanks to its high conductivity and low resistivity.
- Number of Cores and Cross-Section: Determines the amount of current that the cable can carry. The correct cross-section should be selected according to the application.
- Insulation Material: Affects the safety and durability of the cable. PVC is the most widely used insulation material.
- Sheath Material: Protects the cable against external factors. PVC is again the most widely used sheath material.
- Operating Voltage: It is the maximum voltage value that the cable can withstand.
- Operating Temperature: It is the temperature range in which the cable can operate safely.
- Standards: Cables must comply with certain standards (TS, VDE, IEC, etc.).
Things to Consider When Choosing a Plumbing Cable
Choosing the right plumbing cable is critical to safety and performance. Here are some factors to look out for:
- Application Area: It is important whether the cable will be used indoors or outdoors.
- Amount of Current to be Carried: The cable of the appropriate cross-section should be selected according to the power of the devices.
- Environmental Conditions : Factors such as temperature, humidity, chemicals and mechanical stresses should be considered.
- Safety Requirements: Appropriate cables should be selected in terms of fire safety and human health.
- Compliance with Standards: It should be ensured that the cables comply with the relevant standards.
Installation Cables and Safety
Electrical installations contain potential hazards. Therefore, caution should be exercised in the selection and laying of plumbing cables, and the following safety precautions should be observed:
- Installation work must be carried out by authorized electricians.
- Appropriate protection measures must be taken to prevent damage to the cables.
- Grounding installation must be carried out.
- A residual current relay must be used.
Result
Plumbing cables form the basis of the electrical systems of buildings. Proper cable selection and professional installation are indispensable for a safe, efficient and long-lasting electrical installation. For this reason, it is always best to consult an electrician who is an expert in plumbing work and use quality materials. You can rely on Ülkü Kablo to supply the highest quality material.
