What effect does the thickness of the sheath have on the silicone
wire?
I. Defects in material properties. Material properties are not
shown by thickness, but by standard requirements. An index does not
meet the standard, directly affect the quality of silica gel wire.
Two, increase the difficulty of laying silicone wire. Because at
present, the laying of silica gel wire is mainly a bridge or a
pipe, and many enterprises have very tight requirements for silica
gel wire, and the outer diameter is very small. Can be in the
process of laying gap, emit heat energy, to ensure that the outer
sheath of silicone wire is not damaged. Otherwise it will bring
some difficulties to the construction unit and cable laying.
Three, shorten the service life. After the laying of the silica gel
wire, the electricity will be turned on for a long time, and the
electricity will generate heat energy. The allowed working
temperature of the conductor is 70℃, and the allowed working
temperature of the silica gel wire is 180℃ for a long time. The
working temperature will rise in summer, and these temperatures
will be distributed through the outer sheath, and the thickness of
the sheath will increase. The insulation layer of silica gel wire
has a series of physical and chemical changes, losing the original
excellent performance, leading to the obvious decline in the
insulation performance of silica gel wire, and even short circuit,
affecting the normal work.
