To understand the application characteristics and structural features of shielded twisted pair (STP) cables, you first need to understand what they are. Shielded twisted pair (STP) cables are shielded with an aluminum foil outer layer, offering signal shielding and relatively high transmission speeds.
What are the application characteristics of STP cables?
1. Shielded cable performance requirements: Basically the same as unshielded cables.
2. Because they meet shielding (anti-damage) requirements for industrial equipment, they are generally used in environments with moderate to high interference. Cables with plastic sheaths can be buried directly in the ground.
3. The shielding layer must maintain high-quality contact with the connected equipment or be grounded at one end. It must also be non-destructive, non-fragmented, and not easily damaged by external factors.
What are its structural characteristics?
1. Conductive core: Tin plating is permitted in some applications.
2. The shielding density should meet regulatory requirements or be tailored to the user's specifications. The shield should be hand-braided or coiled with tinned copper core wire. If an extruded sheath is required, the shield may be hand-braided or coiled with soft round copper core wire.
3. To prevent internal damage between cores or pairs, a structure with independent phase shielding for each core (or pair) can be manufactured.
Through the above explanation of shielded twisted-pair cable, I believe you have a general understanding of its application characteristics and structural features. Furthermore, the outer layer of shielded twisted-pair cable is coated with aluminum platinum to reduce radiation, but it does not completely eliminate it. Shielded twisted-pair cable is relatively expensive and more difficult to install than unshielded twisted-pair cable.
