SAB Kabel

Insulation & Sheath Material PVC (Polyvinylchloride) for Cables & Wires

What are PVC cables and what are their advantages?

Polyvinylchloride (PVC) - thermoplastic material

PVC stands for "Polyvinylchloride". The application areas for this thermoplast in the plastics industry are diverse. There are various types of PVC used in the wire and cable industry. National (VDE) and International (IEC) Standards Authorities have specified PVC parameters for the different PVC mixtures.

The characteristics of standardized PVC mixtures for the cable industry are defined under the following VDE standards, for example:

  • PVC - insulation mixture EN 50363-3, VDE 0207-363-3
  • PVC - sheath mixture EN 50363-4-1, VDE 0207-363-4-1

PVC that hardens after polymerisation is not suitable for insulating and protecting wires and cables. The necessary mechanical, thermal, and electrical levels can only be reached with the addition of complements such as:

  • softeners
  • stabilisers
  • filler materials
  • slip additives

PVC cables with various insulation and sheathing materials

 

1. SAB-special PVC (Y) - characteristics and advantages

Our special PVC (YA and YM) are used for insulation and sheathing purposes. PVC type YA is used for core insulation and is particularly flexible and has very good electrical characteristics. PVC type YM sheath material has good mechanical characteristics and high flexibility.

The temperature range is as follows:

fixed laying:-40°C bis +70°C
flexible application:+ 5°C bis +70°C


2. SAB-cold resistant PVC (YK) - characteristics and advantages

Cold resistant PVC shows good flexibility and mechanical strength even at sub-zero temperatures. It can also be exposed to various weather influences.

The temperature range is as follows:

fixed laying:-40°C bis +70°C
flexible application:-20°C bis +70 °C


3. SAB-heat resistant PVC (YW) - characteristics and advantages

Heat resistant PVC can resist temperatures up to +105°C. The insulation and sheath materials possess good electrical and mechanical values and have very good heat resistance. The highest valid operational temperature on the conductor itself according to VDE 0207 is +90 °C. Any application above this temperature reduces the usable life.

The temperature range is as follows:

fixed laying:-40°C bis +90°C
flexible application:+ 5°C bis +90 °C
short time use:bis+105 °C


4. SAB-oil resistant PVC (YOE) - characteristics and advantages

Our YOE, TM5 mixtures are oil resistant according to EN 50363-4-1 + VDE 0207-363-4-1. Usually used as a sheath material, it can also be used as insulation.

The temperature range is as follows:

fixed laying:-40°C bis +70°C
flexible application:+ 5°C bis +70 °C

PVC can be classified as inflammable due to its chemical composition. SAB PVC compounds fulfil the criteria regarding burning characteristics according to IEC 60332-1-2 + VDE 0482-332-1-2, UL, VW1, CSA FT1 and FT2. Halogen is however re­leased during a fire, which is a danger to humans, nature, buildings and machines. In addition, PVC control and data cables are not designed for outdoor use.

Application fields of PVC insulated cables

PVC cables are often used for control devices, e.g. Machine tools, flow and assembly lines, conveyor systems, production lines and plant construction, switchgear cabinet construction, communication technology equipment, household appliances, generators, transformers and mechanical engineering, switchgear and control engineering, electrical engineering, installation and packaging technology, textile, woodworking electrical and data processing, in cleaning equipment, automotive industry, automation technology, press and mold making, printing and paper machine construction, surface technology, iron and steel production industry, beverage filling plants, chemical industry, intrinsically safe circuits, control units in explosion- CNC machining centers, lamps and lighting technology, ...
