6.35/11kV Screened Aerial Bundled Cable ABC XLPE Insulated 3 Core Aluminum Conductor with Bare Messenger Neutral

The Screened Aerial Bundled Cable (ABC) with Bare Messenger Neutral 6.35/11kV manufactured by Zhongdong Cable is designed for medium-voltage overhead distribution networks requiring improved electrical protection, mechanical stability, and reliable outdoor performance.

The cable consists of three XLPE insulated aluminium phase conductors assembled around a bare messenger neutral conductor. Each phase conductor incorporates a semi-conductive screen and metallic screen to provide controlled electric field distribution and enhanced protection against electrical stress.

Compared with conventional bare overhead conductors, this screened MV ABC cable reduces the risk of phase contact faults caused by wind movement, vegetation, and external interference. The compact bundled design also helps minimize installation space and improves safety in densely populated or environmentally sensitive areas.

FAQ

Q1: What is the difference between screened 6.35/11kV ABC cable and standard MV ABC cable?
A: Screened MV ABC cable includes metallic screening around each insulated conductor, providing better electric field control and improved protection for medium-voltage operation.

Q2: What is the function of the bare messenger neutral conductor?
A: The messenger neutral acts as both the electrical neutral conductor and the mechanical supporting element, reducing the need for additional support wires.

Q3: Can this cable be installed in areas with limited space?
A: Yes. The compact bundled structure requires less installation corridor space than conventional bare conductor systems.

Q4: Is this cable suitable for outdoor environments with strong sunlight?
A: Yes. The XLPE insulation and UV-resistant HDPE sheath provide reliable protection against sunlight, moisture, and weather exposure.

Q5: What accessories are required for installation?
A: Typical accessories include suspension clamps, anchoring clamps, pole fittings, earthing accessories, and screened cable connection components.

Q6: What is the recommended bending radius during installation?
A: The recommended minimum bending radius is generally 15 × overall cable diameter. Actual installation requirements should follow the manufacturer's recommendations.

Q7: Can this cable be used for renewable energy projects?
A: Yes. It is suitable for medium-voltage collection networks in solar farms, wind farms, and other renewable energy applications requiring reliable overhead connections.
