PVC Double Sheath Power Cable for Industrial Power Distribution | Heavy Duty | Waterproof Manufacturer

PVC Double Sheath Power Cable for Industrial Power Distribution | Heavy Duty | Waterproof Manufacturer

Built for Power Distribution in Harsh Installation Conditions

In industrial environments, power cables are often exposed to mechanical stress, moisture, and rough installation practices such as pulling through ducts or laying across uneven ground. In these conditions, single-sheath cables may suffer from outer jacket damage, which can shorten service life or increase maintenance frequency.

This double sheath power cable is designed to provide an additional protective layer, helping improve durability and reliability in demanding installations.

Typical Installation Scenarios

This cable is commonly used in:

• Outdoor power distribution systems

• Underground duct or trench installations

• Construction sites and temporary power supply

• Industrial yards and exposed routing areas

• Equipment requiring enhanced mechanical protection

In these environments, the double sheath structure helps reduce the risk of mechanical damage during both installation and operation.

Key Functional Characteristics

Enhanced Mechanical Protection
The inner and outer PVC sheaths create a layered structure that improves resistance to abrasion, impact, and handling stress.

Improved Moisture Resistance
The outer sheath acts as a barrier against water ingress in damp or outdoor environments.

Stable Electrical Performance
Designed for low-voltage power distribution with consistent conductivity and insulation performance.

Adaptability for Industrial Use
Suitable for fixed installations where durability is more critical than extreme flexibility.

Cable Construction Overview

• Conductor: Copper or aluminum (Class 2 solid/stranded or Class 5 flexible optional)

• Insulation: PVC

• Inner sheath: PVC bedding layer

• Outer sheath: Heavy-duty PVC

This structure separates insulation and external protection, reducing the likelihood of damage reaching the insulated cores.

Technical Data

• Voltage rating: 0.6/1 kV

• Temperature range: -15°C to +70°C

• Core configuration: 1–5 cores

• Cross section: 1.5–240 mm²

• Standard: IEC 60502-1

• Compliance: CE, RoHS

Double Sheath vs Single Sheath Cable

In installations where cables are exposed or frequently handled, a double sheath design is often selected to reduce long-term maintenance.

When to Consider Armoured Cable

A double sheath improves protection, but in certain cases, an armoured cable may still be required:

• Direct burial without duct protection

• Areas with high mechanical impact risk

• Rodent-prone environments

Armouring (such as steel tape or wire) adds another level of mechanical defense beyond the outer sheath.

Installation Considerations

To maximize cable performance:

• Avoid excessive pulling force during installation

• Use proper cable rollers or guides in long runs

• Ensure bending radius meets installation standards

• For underground use, consider ducting or sand bedding

Correct installation plays a key role in extending service life, even with reinforced cable designs.

Available Configurations

• Copper or aluminum conductor options

• Armoured versions (STA / SWA)

• Flame-retardant or LSZH outer sheath

• Custom core identification and marking

• Project-based cable design

FAQ

Q1: What is the main benefit of a double sheath cable?
It provides additional mechanical protection and better resistance to environmental exposure compared to single-sheath cables.

Q2: Is this cable suitable for outdoor installations?
Yes, it is commonly used in outdoor and exposed environments due to its protective outer sheath.

Q3: Can it be used underground?
Yes, especially in ducts or protected installations. For direct burial, armoured versions are recommended.

Q4: How does it compare to armoured cable?
A double sheath improves durability, but armoured cables provide higher protection against heavy mechanical impact.

Q5: Is it waterproof?
It offers good moisture resistance, but full waterproof performance depends on installation conditions and sealing methods.

Q6: Do you support custom specifications?
Yes, conductor type, sheath material, and structural design can be customized.
