In search of a clean and sustainable energy source for the future, solar remains the most promising renewable energy source for Singapore and most Southeast Asian countries. Singapore aims to harness 1.5 gigawatt-peak (GWp) of solar energy by 2025 and will accelerate the country's goal to at least 2GWp of solar power by 2030.
As a result, there is an increasing demand for Solar PV systems: solar modules, inverters, substructures, plugs, fuses, terminal boxes, and solar cables. In response to the rapidly growing demand of the solar industry, we play our part in contributing to renewable energy sources by providing high-quality Keystone photovoltaic cables that meet stringent requirements.
Construction of a PV cable
Solar cables are double-insulated with cross-linked polyolefin (XLPO). Compared to common power cable insulation such as PVC and XLPE, XLPO has a higher nominal temperature rating of -40°C to 120°C. XLPO insulation has excellent UV resistance, flame retardancy, chemical resistance, and durability. In addition, XLPO is halogen-free, meaning it will not emit toxic gases when exposed to fire.
Using poor-quality solar cables may reduce the lifespan of entire solar PV installations, whereas high-quality solar cables prevent pre-mature ageing processes when installed under appropriate guidelines. To ensure the quality of the solar cables, Keystone solar cables are manufactured in accordance with EN 50618 (H1Z2Z2-K) and certified by TÜV Rheinland.
EN 50618:2014 consists of a series of stringent tests for cables used in PV systems, which include electrical properties test, constructional and dimensional test, insulation and sheathing material test, cold impact and cold bending test, ozone resistance test, weather/UV resistance test on the sheath, dynamic penetration test, damp heat test, shrinkage test, vertical flame propagation and smoke test. The entire testing process is extensive to ensure the quality and reliability of the solar cables.
solar cables are reliable for the entire solar PV system lifespan as they have a service life of more than 25 years under normal use with proper installation.
Pay attention to clamped points or cables that lean over sharp edges to prevent damage to the sheath or insulation.
Do adhere to the minimum cable bending radius. For instance, please do not install the solar cables in a tight loop formation, as it would likely exceed the bending radius.
