NH-VV fire-resistant power cable

Characteristics and uses of fire-resistant power cable NH-VV product: This product has high fire-resistant performance and can withstand direct flame combustion without short circuit or short circuit faults for a certain period of time. Therefore, in the event of a fire, it is beneficial to reduce losses. Low smoke halogen-free cables belong to the category of electrical cables, especially suitable for industries such as power, large buildings, railways, ships, etc. that require high fire safety requirements.
