High temperature superconducting cable initiated power transmission technology revolution;

The structure and development status of superconductor cables are introduced briefly,and the performance of superconductor cables that have been installed to power grid is compared.

A kind of cryogenic orifice plate flowmeter by vacuum insulation is used in the cryogenic LN2 system for 4M-2000A superconductor cable.

Online testing of capacitance in water in communication cable;

Plugging agent introduced in the paper which was especially for bladder communication cable consisted of Part A: polyurethane modifled epoxy resin, reactive diluent and auxiliary material; Part B: polyamine curing agent.

This article discoursed on important action of simple thinking through the design for a product,by looking for a method at measurement of length of breaking communication cable.

Present situation and future development of petroleum jelly used in telecommunication cables and optic fiber cables;

The pertinent electromagnetic shielding analysis of underground telecommunication cables is carried out by means of this numerical algorithm.

A universal model of telecommunication cable surrounded by the buried metal pipeline for calculating their current distribution and shielding effects is presented, which takes the inductive coupling and resistive coupling with each other in the presence of a uniform half space conductive medium(earth) into account.

Status-quo of the standardization of optical fibers, optical fiber cables and telecom cables;
