7pins Waterproof Cable Wire IP67 TPU Trailer Spring Wire Sensor Brake Power Connection Wires

Product information:

Waterproof cable: The outer skin is made of waterproof rubber, and the filling of the cable is also made of waterproof rubber. The jacket of the cable is made of waterproof rubber. It is suitable for submersible pumps, coal mines, underwater operations, water scene lights and other water treatment equipment.

Parameter:

Cable waterproof test method, the longitudinal water resistance of the cable can be tested and judged by the water penetration test of IEC 60502-1997 ANNEX D (normative) or GBT 12706.2-2002 Appendix D (standard catalog); At present, it is mainly determined by indirect methods, such as checking whether the HDPE non-metallic sheath or non-metallic sheath is defective. If these sheaths are determined to be intact, then the cable is considered to have good radial water resistance. However, many users have raised some questions about this method, and caused some disputes and lack of persuasion. Therefore, cable manufacturers and users now urgently need a test method to determine the radial water resistance of the cable. It can avoid the controversy caused by the manufacturer and user due to the lack of the radial water resistance test method.

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 waterproof 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.
