LSZH Cross-Linked Cable Compounds Manufacturers

Polyolefin Cable Compounds for Safer Cable Insulation and Sheathing

Jiangsu Duoshang New Materials Technology Co., Ltd. is a China-based manufacturer of polyolefin cable compounds. We develop and produce low-smoke, halogen-free, flame-retardant, thermoplastic and cross-linked cable materials used for insulation and sheathing across power, communication, rail transit, photovoltaic, new energy and marine cable projects.

Our cross-linked cable compounds manufacturer range is organized around two material families: LSZH Compound manufacturer and B1/B2 LSZH Cable Material supplier. Within these families we offer irradiation cross-linked, UV cross-linked, silane cross-linkable, thermoplastic and higher fire-performance grades so the compound can be matched to the cable design and the end-use environment.

Product Range and Positioning

Each material type answers a different installation condition, fire classification and production route. The table below summarizes how we position the range in projects.

LSZH Compound: Insulation and Sheathing Grades

Our LSZH Compound manufacturer family covers four processing routes. We use the required crosslinking method to select the right formulation, because the production line and cable type determine which material chemistry will work reliably.

• Irradiation cross-linked: Electron accelerator crosslinking gives a uniform three-dimensional network. We supply accelerator irradiation grades for construction engineering, power grids, rail transit and 125°C photovoltaic insulation and sheathing. Explore our irradiation cross-linked LSZH compounds.
• UV cross-linked: UV irradiation provides a fast crosslinking route for small and medium section cables. These compounds suit residential wiring and conventional power distribution lines where line efficiency and lower processing cost are priorities.
• Silane cross-linkable: The A/B system crosslinks after extrusion using moisture, allowing existing thermoplastic lines to produce cross-linked insulation without an accelerator. Silane grades are applied in construction engineering and power grid cables.
• Thermoplastic LSZH sheathing: Thermoplastic compounds are used without a curing step for outer jackets and optical fiber tight-buffered materials. They are a practical choice for communication cables, data center cabling and general LSZH sheathing.

B1/B2 LSZH Cable Material for Higher Fire Requirements

For projects that require controlled reaction to fire, B1 and B2 LSZH grades go beyond conventional halogen-free performance. The material is formulated to limit heat release, reduce smoke density and toxicity, minimize corrosive emissions and avoid flaming droplets during combustion. These properties make it suitable for high-occupancy buildings, hospitals, data centers, transit systems and underground spaces.

The B1/B2 LSZH Cable Material supplier range covers both insulation and sheathing formulations. It includes silane cross-linked, accelerator irradiation cross-linked and UV irradiation cross-linked grades for construction engineering and power grid applications, allowing the cable maker to choose the solution that matches the available production platform.

Material and Specification Fit

We select the starting polymer, flame-retardant package and crosslinking system based on the working point of the cable, the production line and the fire or environmental specification the project must meet. The following parameters define the correct material fit:

• Flame retardancy and fire classification – oxygen index, heat release, flame spread and dripping behavior.
• Smoke and gas properties – smoke density, halogen acid gas content, pH and conductivity, toxicity index.
• Temperature rating – continuous and short-circuit service temperatures, including 125°C grades for photovoltaic systems.
• Mechanical balance – tensile strength, elongation, flexibility, abrasion and crack resistance for installation and service life.
• Processing route – thermoplastic extrusion, silane A/B mixing, UV line or electron accelerator irradiation.

Our proposal states the material grade, recommended processing window and the property targets we can verify during sample evaluation.

Engineering, Quality and Project Support

We operate two production bases with more than ten polyolefin cable compound lines and an R&D center that supports formula design, material analysis, process testing and product optimization. The company follows ISO 9001 quality management system requirements, and the R&D center applies 6S management to keep development and testing consistent.

For overseas projects, we can supply TDS, SDS, product specifications and relevant test and certification documents needed for material evaluation. Documentation is prepared around the specific compound being quoted rather than provided as a generic company profile.

• Formula development for new cable constructions.
• Adjustment of color, flame-retardant package and crosslinking system.
• R&D process testing to support sample evaluation before series production.
• Batch consistency controls across the production bases.

Information We Use to Configure Your Solution

To prepare a suitable configuration and quotation, we need the cable design and operating conditions rather than only a compound name. Please include the following in your enquiry:

• Application field and cable type – construction, power grid, rail transit, photovoltaic, wind power, communication or marine.
• Layer to be filled – insulation, inner sheath, outer sheath or optical fiber tight buffer.
• Conductor material, cross-section and overall cable structure.
• Rated voltage and temperature class.
• Required fire classification and reference standard.
• Crosslinking platform available on the line – thermoplastic, silane A/B, UV or electron accelerator.
• Color, pellet form and packaging requirements.
• Target volume, delivery destination and project timeline.
