Teflon wire specification pdf

Category 5 cable, commonly teflon wire specification pdf to as Cat 5, is a twisted pair cable for computer networks. The cable standard provides performance of up to 100 MHz and is suitable for most varieties of Ethernet over twisted pair. This cable is commonly connected using punch-down blocks and modular connectors.

The category 5 specification was deprecated in 2001 and is superseded by the category 5e specification. The cable is available in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. Permanent wiring used in structured cabling is solid-core.

The category and type of cable can be identified by the printing on the jacket. A Cat 5e Wall outlet showing the two wiring schemes: A for T568A, B for T568B. The category 5e specification improves upon the category 5 specification by revising and introducing new specifications to further mitigate the amount of crosstalk. The category 6 specification improves upon the category 5e specification by improving frequency response and further reducing crosstalk.

Category 5 cable is used in structured cabling for computer networks such as Ethernet over twisted pair. Ethernet connections require two wire pairs. 1000BASE-T Ethernet connections require four wire pairs. Cat 5 is also used to carry other signals such as telephony and video. Cat 5 can carry two conventional telephone lines as well as 100BASE-TX in a single cable. The use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and crosstalk from other pairs. Most Category 5 cables can be bent at any radius exceeding approximately four times the outside diameter of the cable.

If longer runs are required, the use of active hardware such as a repeater or switch is necessary. 24 AWG, or 26 AWG for shorter-distance cabling. 5 is not limited to 4 pairs. The distance per twist is commonly referred to as pitch. Each of the four pairs in a Cat 5 cable has differing precise pitch to minimize crosstalk between the pairs.

The pitch of the twisted pairs is not specified in the standard. Measurements on one sample of Cat 5 cable yielded the following results. Since the pitch of the various colors is not specified in the standard, pitch can vary according to manufacturer and should be measured for the batch being used if cable is being used in non-Ethernet situation where pitch might be critical. Insulated with high-density polyolefin, but not jacketed with PVC and therefore is the lowest of the three in flame resistance. Some cables are “UV-rated” or “UV-stable” meaning they can be exposed to outdoor UV radiation without significant destruction. Plenum-rated cables are slower to burn and produce less smoke than cables using a mantle of materials like PVC.

Plenum-rated cables may be installed in plenum spaces where PVC is not allowed. Archived from the original on 2011-07-10. Cat5 Spec, cat6 specs, cat7 spec – Definitions, Comparison, Specifications”.

Most often these frequencies are not given any special name, and the topic itself is glossed over in most modern texts.

Check up to five results to perform an action. Surf Technologies is a leader in the manufacture of heavy walled PTFE tube, both in standard inch sizes and in AWG sizes. Tube is used in fluid handling applications for high temperature acids and caustics or where contamination is an issue, such as in wire braided hose. In applications where PTFE’s excellent insulating properties are needed heavy walled tube is the shape of choice, e. Surf Technologies extrudes multi-hole tube for the electrical components industry and other users who need multiple tubing cavities. Tube can have two, three, four or five holes for coaxial cable applications, standoffs, and other applications where insulating properties are critical.
