1.We adopt the use of a ZnO ceramic stress control technology to improve electrical field distribution, and at the same time increase operational safety, for the cables subjected to a high voltage.
2. The heat shrink terminators rely on a high-quality heat shrink insulation material which gives the termination excellent insulation, in addition to being a great waterproof and weatherproof material.
3. One of our cable termination kits is of the heat shrinkable type, it has a simple structural design for quick installation, mechanical strength not affected, and adaptability to an environment still good.
Due to different structure in cable terminations and joints, electric field concentration will be easily generated when the medium and high voltage cables in service. These kinds of electric field disturbances may give rise to partial discharge, degradation of insulation material, and equipment breakdown. The difficulty of implementing conventional stress control solutions is that they do not have good stability and at the same time provide good sealing if you are operating the cables outdoors for a prolonged period of time or working in a complex environment.
Our Professional Solution:
Cable heat shrink tubing is a new and innovative cable termination and joint solution specially designed for 15kV to 35kV medium and high voltage power systems. The major advantage is that it uses state-of-the-art ZnO zinc oxide stress control technology which allows for the electric field homogenization via ceramic semiconductor materials. In this way, it significantly mitigates the electric field concentration around cable insulation cut areas.
When it is combined with heat shrinkable insulation tubing and high-performance polymer materials, a reliable sealing structure is made. This structure is able to conform to the irregularities of the cable surface and create a stable connection with the insulation layer to give excellent insulation, moisture sealing, and assure the cable system will work properly for a long time.

Product Advantages:
1. Excellent Electric Field Stress Control Capability.
The heat shrink terminations are based on the use of a varistor ceramic stress control system made from ZnO-based ceramic. It works well to decrease the electric field at locations where the electric field is concentrated by the use of such varistor ceramic materials, which allows for varying of the electric field distribution. When a partial discharge is tested under a 2U₀ test voltage, the partial discharge is less than 5 pC which leads to a lower probability of partial discharge and thereby, it improves the reliability of medium and high voltage cable terminations and joints.
Moreover, the product can withstand both 95 kV and 200 kV of lightning impulse withstand voltage so that the safety margins can be assured even in extreme conditions of overvoltage.
2. High-Performance Insulation and Sealing Protection.
The heat shrinkable cable termination kit consists of an optimized polyolefin and rubber-plastic alloy copolymer material. Following radiation cross-linking treatment, this material is extremely insulated and weather-resistant. The AC withstand voltage test of this material for 5 minutes can be either 39kV for (8.7/15kV) and 117kV (26/35kV), confirming that it has a reliable insulation system and it also is resistant to moisture, pollution, and changes in the external environment.
3. Easy Installation, Improving Construction Efficiency.
A heat-shrinkable outdoor termination set includes a compact layout composed of only few parts. The termination kit can accommodate 1-core and 3-core cables as well as cable diameter ranges of 16-47 mm and 28-60 mm respectively. An array of advantages such as great flexibility, a hassle-free method of fitting, and only minimum tools, which altogether make it less demanding for the worker and more efficient at the worksite.
4. Mechanical Performance and Environmental Resistance.
This line of products has exceptional mechanical strength besides being highly resistant to scratches, corrosion, and bad weather. The maximum apparatus voltage (Um) varies between 17.5 kV and 40.5 kV, making it fit for different application scenarios like outdoor operation, high humidity, and diverse climatic conditions, which in turn guarantee stable and reliable performance for an extended period.

FAQ:
1. How do heat shrinkable outdoor termination kits adapt to the thermal expansion and contraction changes that occur during cable operation?
The heat-shrink structure, combined with highly elastic polymer materials, maintains a tight seal with the cable insulation layer under temperature changes and mechanical stress, reducing insulation risks caused by interfacial gaps.
2. How reliable is the heat shrink outdoor termination during long-term outdoor operation?
The heat shrink outdoors termination has been made of a weather resistant insulation material and a sturdy sealing structure thus enabling it withstand the impact of ultra-violet rays, moisture, pollution and changes in temperature to a large extent. The terminal can be used for cables in outdoor areas where there is a chance of being struck by lightning, etc.
