Shijiazhuang Histe Electronic Co., Ltd was established in 1991. It is the earliest firm to produce prefab cold shrinkable cable accessories domestically. The firm is located in Shijiazhuang Lvdao Development Zone which is close to Qingdao-Yinchuan Super Highway neighboring the second circle-highway around Shijiazhuang city-the junction of Beijing-Guangzhou, Shijiazhuang(short for Shi)-Taiyuan, Shi-Dezhou railway. So its transport is very convenient.
