YJLV 26/35 kV Aluminum Conductor XLPE Insulated PVC Sheathed Power Cable
YJLV 26/35 kV is an aluminum conductor power cable with XLPE insulation and a PVC sheath for medium voltage power distribution. It suits fixed use in ducts, tunnels and protected routes. For buyers focused on cost and project fit, cable size should match the load, site conditions and planned route. Check core count, conductor size and cable accessories before purchase to help avoid costly changes on site. Share your cable schedule, required standard, order volume and drum lengths to get a quote that fits your project and makes bids easier to compare with the same scope and terms of supply.

Overview
YJLV 26/35 kV is an aluminum conductor, XLPE insulated, PVC sheathed power cable for fixed medium voltage distribution installations. For EPC contractors, utility procurement teams and industrial project buyers, it provides an aluminum conductor option when evaluating cable material cost, handling weight and the electrical requirements of a distribution circuit. The cable combines an aluminum conductor with cross linked polyethylene insulation and a PVC outer sheath. XLPE insulation supports a maximum continuous conductor temperature of 90°C under the specified operating conditions. This temperature rating is a design limit, while the permissible current depends on conductor size, installation arrangement and site conditions. Selection should therefore follow the project load calculation rather than voltage rating alone. YJLV has an unarmored construction and is suited to routes such as ducts, tunnels and protected cable installations where the installation design provides appropriate mechanical protection. This makes route planning an important part of purchasing. Where the route exposes the cable to crushing, impact or significant pulling forces, the project engineer should assess additional protection or an appropriate alternative construction. Identifying these conditions before ordering helps avoid material substitutions and installation changes on site. For buyers comparing aluminum and copper cable options, the useful comparison is the complete circuit cost. Conductor cross section, electrical losses, cable dimensions, installation work and termination requirements all affect the purchasing decision. Aluminum conductors require compatible connectors and suitable installation practices. Confirming these details alongside the cable specification helps coordinate cable procurement with accessory selection and site installation. To request a quotation for YJLV 26/35 kV power cable, provide the core count, nominal conductor cross section, total quantity, required drum lengths and installation conditions. Include the project specification, applicable standard, required test documentation and delivery destination so that offers can be compared on a consistent basis. Check the proposed cable datasheet, screen design, overall diameter and accessory compatibility during technical approval. A clear specification gives purchasing and engineering teams a shared basis for evaluating price and technical suitability. With the conductor size, installation route and accessories matched to the circuit, YJLV 26/35 kV can be assessed as a practical solution for projects seeking to control material expenditure while meeting defined distribution requirements.
Key Features
26/35 kV Power Distribution
Rated U₀/U 26/35 kV for medium voltage power distribution. A practical cable option for utility networks, industrial facilities and infrastructure projects with matching system requirements.
Aluminum Conductor Cost Advantage
Aluminum conductors offer a cost-conscious alternative to copper, helping buyers manage conductor material costs and cable handling weight. Final conductor sizing should meet the project's current capacity and voltage drop requirements.
XLPE Insulation Rated to 90°C
XLPE insulation allows a maximum continuous conductor temperature of 90°C. This thermal capability supports circuit design for demanding loads, with current capacity determined by cable size and installation conditions.
Short-Circuit Thermal Withstand
XLPE insulation permits a maximum conductor temperature of 250°C during a short circuit lasting up to 5 seconds. This defined thermal limit supports fault calculations and protection coordination when selecting the correct conductor size.
Protective PVC Outer Sheath
The PVC outer sheath provides an external protective covering for the cable assembly. It helps protect the underlying layers against abrasion during handling and installation along suitably designed cable routes.
Unarmored Design for Protected Routes
Suited to fixed installations in ducts, tunnels and other routes with appropriate mechanical protection. The unarmored construction avoids the additional weight of metallic armor where the installation design does not require it.
