Energy Storage LSZH Cable Compound

These irradiation-crosslinked LSZH / HFFR compounds are developed for energy-storage cable insulation and sheathing used in ESS, BESS and stationary battery-storage systems.

The materials are designed for cable constructions targeting TÜV 2 PfG 2693 requirements, with 90°C and 125°C temperature options available for both insulation and outer sheath applications.

Typical performance includes low surface hardness, -40°C low-temperature winding capability, zero-halogen characteristics, and resistance to acid / alkali, salt fog and UV exposure. Electron-beam irradiation after extrusion is used to achieve the required cross-linked structure, with a recommended irradiation dose of 12-15 MRad.

• 90°C and 125°C matched insulation / sheath material systems
• Low surface hardness for flexible routing in battery racks and ESS cabinets
• Acid / alkali, salt-fog, UV and low-temperature performance data within the series
• Typical halogen content of 0 ppm across the four grades
• Recommended electron-beam irradiation dose: 12-15 MRad

• ESS and BESS power cables
• Battery rack and cabinet interconnection cables
• Stationary battery-storage wiring
• Energy-storage DC cable insulation
• Energy-storage cable outer jackets
• Cross-linked LSZH cable constructions

The 99010 grades are the 90°C route, while the 92510 grades are the 125°C route. Within the same cable layer, temperature class is the main selection factor. The 125°C grades use a 158°C × 168 h aging condition in the supplied data, while the 90°C grades have their own lower-temperature aging conditions.

The I grades are intended for conductor insulation and prioritize electrical insulation performance. The M grades are intended for the cable outer sheath / jacket and are selected for external mechanical and environmental protection. Insulation and sheath grades should not be treated as interchangeable even when the temperature class is the same.

EPC99010-I: 90°C insulation; Shore A 86; 200% elongation; 35% low-temperature elongation rate.

EPC99010-M: 90°C sheath; Shore A 85; 220% elongation; 37% low-temperature elongation rate.

EPC92510-I: 125°C insulation; Shore A 85; 215% elongation; 158°C × 168 h aging.

EPC92510-M: 125°C sheath; Shore A 85; 210% elongation; 158°C × 168 h aging.

Note: Values are typical material data from the supplied product documents. A dash means the corresponding item is not listed in the available grade data. Final finished-cable performance and TÜV 2 PfG 2693 suitability must be verified on the actual cable construction.

• The EPC99010 and EPC92510 Series can be processed on conventional PVC/PE cable extrusion equipment.
• Keep melt temperature at or below approximately 165°C; maximum 175°C.
• A low-compression screw and head are recommended; compression ratio approximately 1:1.2.
• Recommended electron-beam irradiation dose: 12-15 MRad.
• No additional drying is normally required when packaging is intact. After prolonged humid storage, dry at about 70°C for 4 hours.
• Optimize conductor size, insulation/sheath thickness, line speed, cooling and irradiation dose on the actual cable construction..

For grade selection, please provide the target temperature class, insulation or sheath layer, cable structure, conductor size, wall thickness, minimum operating temperature, environmental-resistance requirements and irradiation conditions. Samples can be supplied for extrusion, irradiation and finished-cable evaluation.
