PVC (Polyvinyl Chloride) and XLPE (Cross-Linked Polyethylene) are popular insulating materials for safeguarding various types of wires. Both have their own set of unique properties. PVC is widely recommended by house wire manufacturers and a reliable choice for house wiring systems offering high versatility, affordability, and durable performance. In this blog, we will understand both types and explore the differentiating factors.
Understanding PVC Insulation
Polyvinyl Chloride is a widely prominent synthetic polymer known for its resistance to moisture, chemicals and corrosion. When used for insulation, it is used in the form of a coating around the copper or aluminium wire to protect it from damage, leaking, and environmental factors like heat, water and temperature fluctuations. PVC insulated wires are flexible and easy to install. It provides adequate protection at a low price, making it a cost-effective solution for general-purpose wiring. It can withstand high temperatures ranging between 60-70°C.
Understanding XLPE Insulation
XLPE (Cross-linked polyethene) is a thermosetting polymer with excellent heat and electrical insulation properties. It is made by an advanced cross-linking process which enhances the mechanical and thermal properties. It has superior resistance to heat, wear, chemicals, UV rays, etc. However, due to its advanced manufacturing process, the cost of XLPE increases. For its higher advantages, XLPE is used in extreme conditions like manufacturing units, marine, high voltage applications, power distribution, exposure to harsh chemicals, etc.
What House Wire Manufacturers Recommend
For house wiring, PVC insulation is a go-to option for practical reasons- it gives sufficient protection to the wire and does not cost as much as XLPE insulation. Therefore, house wire manufacturers provide PVC insulated wires for many residential applications, indoor electrical systems, and end users of low-voltage applications etc. Here are key reasons listed to explain why PVC is preferred over XLPE for house wiring insulation:
- Cost Effectiveness: Unlike XLPE which requires advanced technology and manufacturing processes, PVC is easily manufactured by a series of polymerization, compounding, extrusion and cooling. It gives adequate insulation at a low cost.
- Ease of Installation: PVC is lightweight and relatively easier to handle for installation and drawing within the conduits without damage.
- Durability: PVC has long-lasting durability under standard operating conditions. Indoor wiring and residential places are ideal conditions for PVC insulation.
- Standardization and Availability: raw material for PVC is readily available and easy to source for house wire manufacturers. Wire and cable companies like Paraflex craft PVC insulated wires by following standard norms such as IEC, UL, and BS, ensuring uniformity in properties like electrical resistance, thermal stability, and mechanical strength.
Conclusion
PVC is an ideal choice for house wire manufacturers and homeowners alike. It offers ample protection and resistance at high durability and low cost. While XLPE has its advanced set of features, using it for house wiring is impractical unless there is an exceptional case. Paraflex provides unique wires & cables with UNI-R triple twisted strands with triple-layer PVC. They formulate PVC in-house and their house cables have excellent flame retardant characteristics suitable for various working conditions. Choose Paraflex to future-proof your house wiring system.House Wire Manufacturers
