High Temperature Silicone Rubber Cable

Product Overview

High temperature silicone rubber cable is designed for electrical applications requiring stable performance under elevated temperature and demanding operating conditions. This cable is especially suitable for DC-side connections in electric energy storage systems, where thermal stability, electrical reliability, and long service life are critical.

CableApex supplies high temperature silicone rubber cable solutions for industrial equipment, power storage systems, and OEM applications, combining reliable conductor performance with heat-resistant insulation materials.

Applications

This high temperature cable is widely used on the direct current (DC) side of energy storage systems, including:

• Connections between battery modules

• Connections between battery clusters

• Connections between battery clusters and combiner boxes

• Connections between battery clusters and energy storage inverters

These applications require cables with high current capacity, stable insulation, and resistance to thermal and environmental stress.

Cable Construction

The cable structure is designed to ensure electrical stability, mechanical durability, and long-term safety.

• Conductor:
  Tinned copper or bare copper, finely stranded, providing excellent conductivity, oxidation resistance, and current overload capacity.

• Insulation:
  Lead-free XLPO insulation, compliant with RoHS environmental standards.

• Jacket:
  Lead-free XLPO outer sheath, offering mechanical protection, flexibility, and resistance to environmental aging.

• Color options:
  Black, orange, red, or customizable according to application requirements.

Technical Characteristics

• Rated voltage: DC 1500V

• Rated temperature: 125°C

• Reference standard: PPP58049A

• Standards compliance: TÜV SÜD, RoHS, CQC

• Flame performance:
  Passed single vertical flame test
  (IEC 60684-2 & GB/T 18380.12-2008)

The cable features low-smoke, halogen-free, flame-retardant XLPO insulation and jacket, ensuring safety in enclosed or critical installations.

Electrical Performance

Uniform insulation thickness and low eccentricity design help prevent electrical breakdown and ensure consistent dielectric performance. The use of tinned copper conductors improves oxidation resistance and supports long-term electrical stability under continuous load.

Flexibility & Environmental Resistance

This heat resistant cable is designed to operate reliably in both high-temperature and low-temperature environments, offering:

• High flexibility for installation and routing

• Resistance to abrasion, corrosion, and UV exposure

• Stable performance without deformation under bending

The soft yet tough XLPO jacket allows bending and installation without cracking or insulation damage.

Conductor Resistance (Reference)

The following conductor cross-sectional areas are available, with corresponding maximum conductor resistance values (Ω/km) for both tinned copper and unplated copper options:

• 4 mm² – 240 mm²

• Resistance values vary according to conductor size and material selection

(Exact parameters can be confirmed based on project specifications.)
