What Are LOW VOLTAGE CABLES?
Low-voltage cables are insulated electrical conductors designed to transmit electrical energy at voltages up to 1000V AC or 1500V DC.
Basic structure consists of copper or aluminum conductor, PVC insulation (Polyvinyl Chloride), filler layer, and environment-resistant outer sheath.
These cables are vital components in building installations, industries, and public infrastructure for final power distribution to consumer devices.
The main standards applicable in Indonesia are SNI IEC 60227 and SNI IEC 60502, ensuring safety and optimal performance.
Main Functions of LV Cables
1. Final Power Distribution: Delivering electricity from distribution panels to end loads (lighting, motors, etc)
2. Building Installation: Connecting electrical networks in offices, residences, and public facilities
3. Control Systems: Operating industrial control and automation devices
4. Underground Networks: A Safe outdoor installation alternative
5. Fire Protection: Special design to maintain operation during fires
Types of Low-Voltage Cables
1. NYY Cable (Single Core PVC Insulated)
Single-core cable with PVC insulation, used for fixed installations in conduit or duct. Class 1 or 2 copper conductor with cross-section 1.5mm² to 500mm². Suitable for household installations and general lighting with a max operating temperature of 70°C.
2. NYM Cable (Multicore PVC Insulated)
Multi-core cable (2-5 cores) with individual PVC insulation and PVC outer sheath. Has a filler layer between conductors for round shape. Used for fixed installations in buildings with mechanical protection. Resists temperatures up to 70°C with medium flexibility.
3. NYY Cable (Armoured PVC Sheathed)
Steel armoured cable with PVC outer sheath. Designed for direct burial installations or areas with mechanical damage risk. Construction: conductor + PVC insulation + PVC tape + steel armour + PVC sheath. Resistant to water, oil, and chemicals.
4. NYFGbY Cable (Fire Resistant)
Fire-resistant cable with special construction using mica tape and special composites. Maintains function during fire (750-950°C) for 90-180 minutes according to IEC 60331. Used for building safety systems, fire alarms, and evacuation routes.
5. NYAF Cable (Flexible Cord)
Flexible cable with class 5 conductor (stranded fine wire) for applications requiring high flexibility. Used for portable equipment, industrial machine connections, and frequently moved applications. Resists bending up to 30,000 cycles at 5xD cable radius.
6. NYYHY Cable (Halogen Free)
Halogen-free cable with Low Smoke Zero Halogen (LSZH) insulation and sheathing materials. When burned, it produces minimal smoke and no corrosive gases. Mandatory for enclosed public areas like airports, hospitals, and high-rise buildings.
