• IEC 62930 - 2017 (Rated voltage 1.5kV DC photovoltaic cable, etc.)

Product Description

• PV1-F 1×70mm² is a DC interconnection solar cable designed for the DC side of photovoltaic systems, suitable for 1.5 kV DC applications using cross-linked polyolefin insulation.
• Rated for continuous operation with maximum conductor temperatures up to 120°C.
• Multiple cables may be used in parallel when required by system design.

Technical Specifications and Electrical Performance

• Construction: Halogen-free, flame-retardant cross-linked polyolefin insulation and weather-resistant outer sheath.
• Rated DC voltage: up to 1.5 kV (typical for single-core/non-grounded PV systems).
• AC test voltage capability: AC test pulses up to 3.5 kV (dielectric strength validated by testing).
• DC test voltage reference (manufacturer test context): examples cited such as 15 kV/5 min in documentation for high-voltage testing.
• Operating temperature range: -40°C to 120°C (mobile or fixed). Maximum permissible temperature rise in cable trays: ≤ 20°C.
• Good resistance to UV, ozone, oils and weathering for outdoor longevity.
• Minimum bending radius: ≥ 4 × cable diameter (to facilitate routing in trays and conduits).

Industry Utilization and Application Value

• Designed primarily for DC interconnections in photovoltaic arrays: between PV modules, to combiner boxes, and inverter DC input wiring.
• Appropriate for rooftop and ground-mounted solar farms where outdoor durability, UV/ozone resistance and long service life are required.
• Intended for use by solar project developers, system integrators, electrical contractors and cable suppliers requiring standardized PV-rated cables.

Product Advantages

• Structural design uses halogen-free, flame-retardant cross-linked polyolefin for insulation and sheath, reducing fire hazard and improving chemical/ozone resistance.
• Rated for high DC voltages (1.5 kV) and withstands high AC test voltages (e.g., 3.5 kV), supporting dielectric reliability in PV systems.
• Wide operating temperature range (-40°C to 120°C) and UV/weather resistance for long-term outdoor performance.
• Relatively small minimum bending radius (≥ 4× diameter) eases installation in constrained conduits and cable trays.
• Designed to reduce maintenance frequency and operational risk in outdoor electrical networks.
