High energy X-ray telescope (HE) is one of the three instruments of Insight-HXMT(Hard X-ray Modulation Telescope) payload. The HE detector (HED) array is composed of 18 actively NaI(Tl)/CsI(Na) phoswich scintillators with a total geometric area of ~ 5100cm^2 and cover the energy range 20-250 keV. In this paper we describe the on-ground detector-level calibration campaigns and present the principal instrument properties of HEDs.
