Suzhou Feibo Heat and Cold Shrinkable Products Co., Ltd. originally used only heat shrink products such as heat shrink tubes. After two or three years of stability, it expanded its business scope and began to research and produce cold shrink products, and promoted sales nationwide. Since the development of cold shrink products, the sales volume has been almost the same as that of heat shrink products, but the profit ratio of cold shrink products is much higher than that of heat shrink products. Today we will talk about one of our hot-sell products in Suzhou Feibo - high voltage cold shrink cable accessories.

The main raw materials for high voltage cold shrink cable accessories are silicone rubber and ethylene-propylene rubber. Suzhou Feibo Heat and Cold Shrinkable Products Co., Ltd. adopts imported liquid silicone rubber as a whole, which has high elasticity and convenient product inspection. Suzhou Feibo's high voltage cold shrink cable accessories use a reinforced stress cone structure to reduce the degree of deformation of the stress cone during expansion and enhance the sealing effect at the end. The current high voltage cold shrink cable accessories are all composite pre-expansion technology, which can realize rapid shrink-down installation, significantly shorten the construction and installation time, reduce manpower and material resources, and improve the installation quality of cable accessories and the safe and stable operation of cables.

The high voltage cold shrink cable accessories of the straight-through intermediate joint adopts an integral prefabricated structure. The cold shrink cable attachment has white plastic support strips inside, which maintains the outer diameter of the cable insulation with a single side larger than 3 mm, and the interface pressure is greater than 3MPa, after shrinking, it can ensure sufficient pressing force at the insulation interface. The cable insulation intermediate joint has a double seal of copper shell and FRP waterproof shell, and is filled with a water-proof pouring agent which is cured at room temperature to ensure its good waterproof performance. The high voltage cold shrink intermediate joint has strong mechanical strength, can achieve the same insulation level as the outer sheath of the cable, and can withstand the impact of a certain mechanical external force.

Although the price of cold shrink products is much higher than that of heat shrink products, this is due to raw materials and production technology, but the high voltage cold shrink cable accessories of Suzhou Feibo are worthy of believable.
