The invention discloses a shielding high-speed enhanced CAT 7 type data communication cable which comprises eight copper leads and a cross skeleton. A sheath layer wraps a tinned copper wire braided layer. The sheath layer comprises 100 parts by weight of 1,3-butadiene, styrene, ethane-vinyl acetate copolymer, ethane-vinyl acetate copolymer grafted maleic anhydride copolymer, siloxane, vapor-phase-method white carbon black, cooper powder, microcrystalline wax, titanium white, 4,4'-bis(alpha,alpha-dimethylbenzyl)diphenylamine, dicumyl peroxide, triallyl cyanurate and dilauryl thiodipropionate. The pitches of first, second, third and fourth twisted pairs are 15.2, 13.7, 14.4 and 12.9 mm respectively. The shielding high-speed enhanced CAT 7 type data communication cable improves reflection and absorption of high-frequency electromagnetic waves, reduces crosstalk and signal attenuation, broadens the bandwidth of adsorption frequency, and enhances the stability of product performance.
