Guide to Choosing Polycab 16 Sq Mm 4core Armored Cables

Cable selection plays a critical role in ensuring the safe and stable operation of electrical power systems. In three-phase power distribution networks, choosing appropriate cables requires careful consideration of technical specifications and application requirements. This analysis examines key factors using a 16 sq mm four-core aluminum-armored cable as a reference case.

The examined cable model features:

• Four-core design with XLPE (cross-linked polyethylene) insulation
• Underground direct burial installation capability
• Standard 1000-meter reel length
• 220V rated voltage
• 50-ampere current carrying capacity under normal operating conditions

In three-phase four-wire systems, this cable configuration can simultaneously transmit three-phase power and neutral current. Typical applications include:

• Industrial power distribution for small manufacturing facilities
• Commercial building electrical systems (lighting, HVAC, etc.)
• Residential power supply for household appliances and lighting circuits

• Ambient temperature variations impact current carrying capacity
• Installation method (direct burial, conduit, etc.) influences heat dissipation
• Safety margins should exceed calculated load requirements

Proper installation according to electrical safety standards and regular maintenance inspections of insulation integrity are essential for long-term system reliability. Potential safety hazards should be identified and addressed through periodic testing protocols.
