Outdoor LED 500mm IP67 M15 Female And Male Cable

M15 Waterproof Cable Wire Black PVC Outdoor Waterproof LED Female And Male Connection Wires

Product information:

The waterproof method of cable is generally divided into two kinds of longitudinal water blocking and radial diameter water. Longitudinal water-blocking commonly used are water-blocking yarn, water-blocking powder and water-blocking tape, their water-blocking mechanism is that these materials contain a water-swellable material, when the water is from the cable end or from the sheath After entering the defect, this material will quickly expand with water to prevent the water from further spreading along the longitudinal direction of the cable, thus achieving the purpose of longitudinal waterproofing of the cable. Radial water blocking is mainly achieved by extruding HDPE non-metallic sheath or hot pressing, welding, cold drawing metal sheath.

Parameter:

For XLPE insulated cables above 110kV, metal sheath is mainly used to make the cables meet the waterproof requirements. The characteristic of the metal sheath is that it is completely impermeable, so the cable with the metal sheath has very good radial water resistance. The main types of metal sheath are: hot-pressed aluminum sleeve, hot-pressed lead sleeve, welded wrinkled aluminum sleeve, welded wrinkled steel sleeve, cold drawn metal sleeve, etc.

The quality of the wire harness material directly affects the quality of the wire harness. The choice of wire harness material is related to the quality and service life of the wire harness. In the selection of wire harness products, don't be greedy for cheap, cheap wire harness products may use poor quality wire harness materials. How to distinguish the quality of the harness? Understand the material of the wiring harness. The following is the material of wire harness selection.

The wiring harness is generally composed of wires, insulating sheaths, terminal blocks and packing materials.

1. Material selection of terminal

The copper used for terminal materials (copper parts) is mainly brass and bronze (brass is slightly lower in hardness than bronze), of which brass accounts for a larger proportion. In addition, different coatings can be selected according to different needs.

Second, the choice of insulating sheath

The commonly used materials of sheath material (plastic parts) are PA6, PA66, ABS, PBT, pp, etc. According to the actual situation, flame retardant or reinforcing materials can be added to the plastic to achieve the purpose of reinforcing or flame retardant, such as adding glass fiber reinforcement.

Third, the choice of wire harness

According to the different use environment, choose the corresponding wire material.

Fourth, the choice of dressing materials

Wire harness bandaging plays the role of wear resistance, flame retardant, anticorrosion, interference prevention, noise reduction, and beautification of appearance. Generally, the bandage material is selected according to the working environment and the size of the space. There are usually adhesive tapes, corrugated pipes, PVC pipes, etc. in the choice of packing materials.
