( MICROTEK) SOLAR CABLE 4 Sq mm - UV Resistant 100 Mtrs

KEY FEATURE

ENERGY EFFICIENT CABLES: Microtek Cables provides the highest level of electrical conductivity to 101% copper conductivity, exceeding the parameter specified by the International Annealed Copper Standard (IACS). This guarantees a minimal loss over the entire length of the cable, which translates into a saving of 2 to 3% on the electricity bill. It also offers added protection from voltage fluctuations.

LOW VOLTAGE DROP: The voltage drop from the supply point to the final receiving point is called voltage drop. A fall of high voltage through the conductor is undesirable because it reduces the energy provided. Microtek wires and cables have the right conductor diameter to ensure a low voltage drop and greater efficiency when using electric equipment.

SHORT-CIRCUIT PROTECTION: The fire caused by a short circuit is the current electric accident. A short circuit can be caused by a host of reasons, such as faulty wiring, broken insulation due to the inferior quality of the insulation, overloaded circuit and faulty plugs, switches, cords and receptacles etc. Microtek wires guarantee superior insulation and conductor characteristics to avoid short circuits caused by wiring.

HIGHER Di-ELECTERIC STRENGTH: The di-electric force represents the magnitude of the voltage supported by a wire test piece when a specified voltage is passed through it for a specified length of time. Higher dielectric resistance means better electric characteristics. PVC compound used for manufacturing Microtek Cables offers high di-electrical resistance to prevent electrical failure in PVC.

HIGHER CONVECTION OF HEAT: Convection is the heat stream from the hot region to the cold region. Lubricants like wax are required to prevent PVC-melt from sticking to the hot extrude surface which ensures a good heat transfer within the wire resulting in higher convective heat dissipation capability.

WATERPROOF AND UV RESISTANT: In many buildings, constructional concrete may not be waterproof. Contact with water results in degradation of the electrical and mechanical properties of the cable. Exposure of cable polymer to UV radiation induces chemical processes that cause polymer damage like chalking, loss of impact or tensile strength and a host of other chemical changes. All this can greatly reduce the service life of the cable and expose people to electrical shocks.

Applications

These cables are suitable for permanent outdoor long-term use, under variable and harsh climate conditions. They are designed and tested to operate at a normal maximum conductor temperature of 90°C and for 20,000 hours up to 120°C. Therefore, the expected period use is 30 years under normal usage conditions.
