A cable's current capacity does not come from the cross-section alone. Check the conductor material, insulation, installation method, ambient temperature and the grouping of circuits together with the reference table.

Voltage drop depends on the current, the length of the route and the cable's impedance. Learn the single-phase and three-phase formulas, a numerical example and the difference between the route's drop and the network's drop.

The difference between XLPE and PVC is not only temperature tolerance. Compare where the insulation and sheath sit, the installation conditions, fire behavior and connection specifications before choosing.

Flexible cable is made of fine multi-strand conductors. Learn the difference between a core and a strand, conductor class, flexibility limits and tips for ordering this cable, with examples.

In the market, "solid cable" and "fixed-installation cable" are sometimes used for each other. Separate Class 1 and 2, fixed-installation use and bending limits.

A cable fire can start from overload, an unreliable connection or damaged insulation. Learn the signs of danger, the differences between faults and a safe way to investigate.

Cable heat can come from a heavy load, a faulty connection or poor installation conditions. Learn the difference between heat along the route and local heat, and carry out troubleshooting safely.

To choose an air conditioner cable, the BTU capacity is not enough. Review the electrical specifications, where the supply enters, the route length and the model's manual together.

Horsepower is not enough to choose a pump cable. Check the nameplate current, the route length, whether it is single-phase or three-phase, the starting method and contact with water.

An elevator doesn't have a single cable. The fixed supply, the motor connection and the travelling cable have different needs; settle the mechanical and communication criteria before ordering.

See the approximate weight of several Afsharnejad cable models with clear units. Keep the full cable weight separate from the conductor weight, the copper index and the reel weight.

Get to know Khorasan Electric (Afsharnejad), Shahid Ghandi and Yazd Wire and Cable by product area, and learn what documents to ask for when comparing brands.

Two prices can be compared when the product specifications, the quantity, the currency and the delivery terms are the same. Put these side by side first; then look at the price difference.

A monitoring system consists of a sensor, a communication path, software and someone responsible for responding. Before expanding it, test its behavior when the connection drops and when conditions change.
