Overhead Insulated Wire
Summary:
Overhead lines are divided into low voltage and high voltage. General models are divided into many types. For example, for street lamp overhead lines, JKLYJ * 10KVA * 50*100 indicates the voltage, model, material, cross-sectional area and length of the core.

Product Details
The so-called overhead line is relative to the cable, that is, the tower will be set up in a certain height of the wire transmission power line. The ground insulation of overhead lines in high-voltage transmission and distribution networks is generally air-based. The previous distribution lines (below 10kV except 380V) also generally use bare wires. However, due to the complex distribution environment in urban areas, short-circuit grounding and lightning strike lines often occur, resulting in reduced power supply reliability. Therefore, insulated wires (I .e. the outer layer of wires is wrapped with insulation) are generally used for overhead lines below 10kV at present, which is the so-called insulated overhead lines.

Good Cable Made by Huaqiang
Good cable, copper core is the key
High purity oxygen-free copper, anti-aging, high conductivity, low loss. Super current load capacity.
Good cable, low resistance
The resistance is small and the conductivity is higher. The resistance directly affects the consumption of current in the transmission process. The smaller the resistance, the more energy-saving.
Good cable, the insulation layer should be uniform thickness
To prevent breakdown and ensure safety, Huaqiang adopts high-quality equipment to ensure the low eccentricity and uniform thickness of the cable, effectively prevent the breakdown of wires and cables, and ensure safe use of electricity.
Good cable, safety and environmental protection first
Layer by layer testing and conscience checking, Huaqiang insists on defending the quality of national seiko, does not contain lead, cadmium, hexavalent chromium, mercury and other heavy metals, does not contain brominated flame retardants, and does not produce harmful halogen gases and corrosive gases.

FAQ
01
What if the project cannot be delivered due to unstable cable performance?
02
What if the cable cannot be delivered on time and the project cannot proceed as scheduled?
03
For the same project, we need to find four or five cable factories to purchase all cables. can we not purchase all cables in one stop?
04
In the test of winter and heat, the safety performance of wire and cable can stand the test?
