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.
