The PLB ducts are an innovative invention for protecting cables. Because cables like optical cables and broadband cables are sensitive and expensive, they require robust protection, which is not possible by ordinary ducts. Underground cabling has testing conditions that require a suitable duct that provides an efficient shield to the cables. Therefore, the PLB Ducts Manufacturers make top-tier quality ducts that are needed for various cabling installation and protection needs. If you need a PLB duct for your construction project, several factors need to be taken into consideration when choosing the best manufacturer. This blog explains all those factors.

Main Factors to Consider

Know Its Key Purpose

The PLB duct is composed of two layers- outer and inner. The outer layer is made of high-density polyethylene (HDPE), while the inner layer is permanently lubricated and made of silicone and HDPE. Due to permanent lubrication, it enables less friction while drawing the cables via pulling or blowing methods.

Intended Application

These ducts are crafted for telecom cables, power cables, broadband infrastructure, highway projects, and railways. Consider where you are going to use this cable, as it helps in deciding the size required.

Product Specifications

The PLB duct should be easily bendable through rough undergrounds and not degrade its quality. It should be able to draw cables over long lengths, reducing the need for heavy equipment, fittings, and joints. Its key properties are lightweight, corrosion and abrasion resistance, slow crack growth resistance, durability, and UV resistance.

Manufacturer’s Credibility

Check for the experience, expertise, and range of customization provided by PLB Ducts Manufacturers. Look for the warranty provided by them, as PLB ducts can last up to 50 years of service. Custom services and warranties build trust between manufacturer and buyer.

Standards and Approvals

The standard compliances of PLB Ducts Manufacturers are IS:7328-1992 or ISO 1183 & ISO 1133, EC (Telecommunication Engineering Centre) standards, UV-grade, and CACT (Cable Acceptance Certification Test) approved. These approvals and certifications ensure quality and evade the risk of purchasing from an unreliable manufacturer.

Conclusion

PLB ducts are a highly essential element in modern telecommunication and underground cabling infrastructure. By considering the factors mentioned above, one makes a well-informed decision in choosing the right PLB Ducts Manufacturers for their respective projects.
