Large-pair cables (25/50/100/200/300 pairs HYA/HYAT/Low Smoke Halogen-Free LSZH Category 3/Category 5) are the core cables for government low-voltage voice backbones. Primarily designed for high-capacity analog voice transmission, they also accommodate emergency calls, security control, fire alarm linkage, and low-speed alarm signals. Suitable for confidential, highly stable, and multi-extension government scenarios, outdoor armored versions are used for inter-building installations in industrial parks and municipal pipeline networks.
