PV Cable
Walsin Lihwa PV cables have EN, UL, and S-JET certifications. PV cables are always used under high temperatures and must be resistant to heat, humidity, and sunlight. The UL, for example, requires USE-2 cables and PV cables stand for temperature higher than 90°C in a humid environment. PV cables are installed outdoors and also must pass a 720-hour weatherproof test as well as a -40°C low-temperature resistance test. The structure of PV cables is relatively simple and uncertified PV cables cannot reach the product life expectancy. Replacing uncertified PV cables is very costly and troublesome; on the other hand, certificated PV cables save maintenance costs significantly to enable more cost-efficient solar power generation.
