Crosslinked Polyethylene insulated Thermoplastic sheathed cables for working voltages up to and including 1100 V

1. Scope

The standard defines the scope and purpose, which is to establish requirements for crosslinked polyethylene insulated cables with thermoplastic sheathing for electrical installations with working voltages up to 1100 volts.

2. Materials:

It specifies the materials used in the construction of these cables, including the crosslinked polyethylene insulation and the thermoplastic sheathing.

3. Design and Construction:

S 7098 (Part 1) outlines guidelines for the design and construction of these cables, including conductor size, insulation thickness, and other construction details.

4. Quality Control

Manufacturers of these cables are typically required to implement quality control measures to ensure that their products meet the specified requirements, including factors such as insulation thickness, conductor quality, and overall cable integrity.

5. Testing and Inspection:

The standard may include testing and inspection procedures to verify the cables' compliance with the standard. This can encompass tests for insulation properties, electrical performance, and other relevant factors.
