0.6/1kw Tunnel PVC Insulated Power Cable
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.

Application
PVC insulated power cables are suitable for transmission and distribution systems with a rated voltage of 0.6/1kV. For fixed installation in the open air, buried directly in the cable trough. Steel tape armored (STA) cables can withstand mechanical forces, but cannot withstand large tensile forces. Steel armored (SWA) cables can withstand mechanical and tensile forces.
