SIP-5ng / AsXSn Flame-Retardant Self-Supporting Insulated Aerial Cable

Product Overview

SIP-5ng / AsXSn is a flame-retardant self-supporting insulated aerial wire designed for low-voltage overhead power distribution networks. It features stranded aluminium conductors and UV-resistant cross-linked polyethylene insulation formulated with flame-retardant properties.

The insulated conductors are twisted together in a right-hand direction, with a twisting pitch not exceeding 450 mm. The design is intended for overhead power lines and electrical distribution networks with a rated voltage of 0.6/1 kV and a frequency of up to 50 Hz.

SIP-5ng is suitable for residential power distribution, overhead network construction, and applications where improved fire performance and reduced electrical clearances are required.

Construction

• Conductor: Round, stranded, compacted or sealed aluminium conductor; nominal cross-sections from 16 to 120 mm².
• Insulation: UV-resistant, light-stabilized cross-linked polyethylene (XLPE) with a flame-retardant formulation.
• Assembly: Insulated conductors twisted together with a right-hand lay direction and a maximum twisting pitch of 450 mm.
• Supporting element: To be confirmed according to the final approved construction.
• Rated voltage: 0.6/1 kV.
• Frequency: Up to 50 Hz.

Applications

SIP-5ng / AsXSn is designed for:

• Low-voltage overhead power distribution networks.
• Residential and urban electricity supply.
• Overhead power line construction in areas with buildings and other structures.
• Distribution networks requiring flame-retardant insulated conductors.
• Aerial cable installation along building facades, where permitted by applicable installation regulations.

Key Features and Benefits

Flame-Retardant Insulation

The insulation is formulated to resist flame propagation. The applicable flame-retardant test method and performance classification should be confirmed against the project specification.

UV-Resistant XLPE Insulation

Light-stabilized cross-linked polyethylene insulation is designed for outdoor exposure and resistance to ultraviolet radiation.

Reduced Risk of Electrical Contact

Insulation helps reduce the risk of phase-to-phase contact and accidental contact with nearby objects compared with bare overhead conductors, subject to the applicable installation requirements.

Compact Overhead Installation

The insulated bundled construction can help optimize overhead line arrangements and may allow reduced installation clearances where permitted by local regulations.

Aluminium Conductors

Stranded aluminium conductors provide an economical, lightweight solution for low-voltage overhead power distribution.

Building-Facade Installation

The cable may be installed along building facades in accordance with the relevant electrical installation rules and project requirements.
