Coaxial Cable
Coaxial cable is a kind of electric cable which is widely used in computer network and plays an increasingly vital role in our modern life. The coaxial cable can be applied in constructions of video monitoring lines and video conference system, transmission of engineering fitment signals and video signals, connection of the audio-visual facilities, etc.HEFS makes our electric cable superior to other similar products by taking the international experience and advanced technologies. HEFS series coaxial cables have four kinds: HEFS-4001, HEFS-4002, HEFS-4003, and HEFS-4004. These coaxial cables are made of high-grade materials with great resistance of electromagnetic interference so as to improve the correspondence quality.
HEFS series coaxial cables are ideal electric cable for their reliable quality and convenient installation program. We can design your favorite coaxial cables as per your needs. Customer is the core of HFES in China. We will continue to offer sound quality speaker cables, power cables, network cables and first-rank services.
