Solar Cable Performance Requirements

solar cable

solar cables, also known as cables PV, are the components of the solar system to connect the panels of the photovoltaic power system. Photovoltaic power generation is based on the principle of photovoltaic effect.

Uses solar cells to convert energy from sunlight directly into electricity. Photovoltaic power systems consist of three main components: solar panels, regulators and inverters.

Aluminum cables: A Strong Competitor of Copper Wires

aluminum wires

Cables are the heart of any electrical project. Whether it is an interior or exterior project, an underground or aerial installation, cables are the key.

So, What type of the cable should we choose? Copper or aluminum cable? Does the cable need reinforcement? (usually steel)?

In this article we will explore these issues and explain why aluminum cables may be more suitable than other options for certain types of power transmission..

Introduction to High Temperature Superconducting Cables

high temperature superconducting cable

The power transmission by high-temperature superconductors is one of the most revolutionary engineering technologies in the energy industry today.

The term high-temperature superconductivity refers to the use of superconducting materials in an environment of liquid nitrogen a -200 Celsius degrees, near absolute zero.

In this case, the resistance of the energy transfer medium is close to zero and energy transfer losses are practically non-existent.

Methods to Check the Quality of Coaxial Cables

coaxial cables

Coaxial cable is a cable that consists of a copper conductor, an isolation, a woven net and an outer cover. It can be used for transmission of analog and digital signals, including cable tv, long distance telephony, local area networks of computers, etc.

The quality of the coaxial cable has a major impact on the quality of the signal transmission. The following are ways to check the quality of coaxial cables.

Electrical cables security and firefighting

electrical power cable

In recent years, A variety of electric cables fireproof, fire resistant and high temperature resistant, have achieved certain results.

These electrical cables do not spontaneously burn, have a certain flame retardant role, in fire they can hold a certain amount of energy, communication time.

But these cables also have a great shortage, since the cable in the fire will emit toxic gases and smoke. affecting vision, etc., in the evacuation and rescue of personnel to buy time and at the same time bring fatal injuries to personnel.
