PVC insulated power cable
PVC (polyvinyl chloride) is widely used for insulation, coating and
sheathing of cable structures. PVC is cost-effective and has
excellent aging properties, usually exceeding a life span of 25 to
30 years.
Because PVC is easy to modify, it is considered to be one of the
most versatile thermoplastics-although PVC is inherently hard and
hard, it is easy to pass plasticizers, stabilizers, lubricants and
various other auxiliary ingredients And fillers are modified and
processed to enhance various properties. When used as a
thermoplastic type, it is also easy to process and recycle.
Cables with PVC insulation or sheath are flame retardant, which is
an important consideration for cables in most applications. PVC is
resistant to many chemicals, including oils, acids, and alkalis,
and is tough, durable, and wear-resistant. Adding various additives
can improve its temperature range (usually -40 to 105°C), as well
as its resistance to sunlight, reduce smoke and dust emissions and
improve water resistance.
As an insulating material, cables can usually only choose between
XLPE and PVC-between thermoplastic and thermoset materials. There
are thermosetting PVC cross-links, which are usually cross-linked
using electron beam technology, but are more expensive to use, so
when specified, they are usually used in high-spec applications in
industries such as defense and automotive. Thermosetting or
cross-linked polyvinyl chloride has higher heat resistance, tougher
and better dielectric strength, which means that thinner coatings
or insulating layers can be applied, resulting in a smaller overall
cable size.
