If conventional cable bend radius is less than the minimum radius, the cable insulation can’t reach standard thickness because of convex curvature of cable end excessive bending, thus affecting the insulation effect, lead to cable breakdown, or even cause a fire or other accidents.

Control cables are used in factory equipments, power plants, switchgear, and where there is control equipment

Flexible wires and cables are widely used in factory machinery, mining machinery and mobile equipments and so on.

You can get H07RN-F cable size by checking the printing word on cable or measuring the single wire of the conductor with micrometer, and then count all wires of conductor.

Protection material of high tension wire which greater than 11kV is XLPE insulation

Standard RF Coaxial Cable cross-section is rounded, the cable outer shield, aluminum foil affixed to the outer surface of the insulating medium, the outer surface of the medium, the more rounded, the smaller the gap between the aluminum foil and its appearance, the more rounded the gap becomes.

DC voltage cable insulation volume resistivity of the electric field distribution depends on the material, and the electric field distribution depends on the AC voltage of each of the dielectric constant of the medium, especially in the DC cable terminal head, connector boxes and other cable accessories in alternating electric field intensity distribution and the distribution of the field strength is completely different, and the mechanism and the mechanism of aging DC voltage AC voltage insulation aging is not the same.

For class Ⅰ signal cables must be shielded cables, class Ⅰ signal millivolt signal, the strain signal should be shielded twisted pair cable, but also to ensure that the shield is only a little ground, and to a good grounding. This can greatly reduce the electromagnetic interference and electrostatic interference.

Power cables outermost layer is generally rubber or synthetic rubber sleeve, this layer is not only insulation layer, but also play a role to protect cable from harm.

THHN and THWN are all nylon sheath electric wire, one type of American Standard electric wires, they are according to UL62 and UL83 Standard.
