UTP cable Construction illuminate:
* Twisted bare copper or single soft copper conductor
* Insulating material (solid polyolefins(PE),Low Smoke without fire-retardant polyolefin chlorine(LSNHP), fluorine B-propylene-wide(FEP)
* Jacket materials (PVC, Low Smoke without fire-retardant polyolefin chlorine(LSNHP), fluorine-containing polymers(FEP)
* Can increase the special features (moisturproof, enhance strengthening, etc.)
* Can choose special structure (for double-jacket, etc.)

Uses: The horizontal twisted cable use in digital communication,which useing in the cabling between the communication lead out end and the connect area wire framein the building or dwelling house synthesis cabling system work area. In order to meet the different reuqirements of users, this cable define into STP and UTP.
STP cable will be free from outside interference and reduce error, STP cable general used in hospitals, Telecommunications, airport and ect.This cable's standard cabling long is 90 m, and using the T568A or T568B installed method.
