1. This set covers various power systems from 1 volt low voltage up to 36kV medium/high voltage. It is an excellent choice for installing terminations on single-core and three-core XLPE power cables for the use of the cable terminations in distribution at any level.
2. A heat shrinkable cable termination kit can help to even out the electric field distribution so as to minimize the possibility of partial discharges and at the same time enhance the operational reliability of cable endings.3. There are several advantages of heat shrinkable termination: it has capabilities as the insulator, sealant for preventing water, and mechanical protection, and is widely applied in substations, urban power grids, industrial power distribution, renewables, and rail transit.
When the cable's outer shielding is removed in power system termination, the electric field can be heavily focussed at such location. A poor termination design might cause different problems like partial discharge, distortion of electric fields, flashover under water and insulation aging. Beside that, the constant exposure of terminations to UV light, rain, temperature fluctuations, and mechanical stress reduces their service life and raises the maintenance costs, respectively.
Professional Solution:
In order to handle these problems, our heat-shrinkable cable terminations make use of high-grade cross-linked polyolefin (XLPO) materials and have a multi-layer protective structure with stress-control tubing, electrical insulating tubing, and rain sheds. After the heat-shrink installation, the terminations become an almost perfect fitting with the cable, forming a single layer of insulation and sealing system with no visible seams, thereby, ensuring electric field homogeneous distribution, stopping the moisture penetration, preventing partial discharge and insulation failure, and at the end, the power system is safe, stable, and operates for a long time.

Advantages of Multi-core Heat Shrink Terminations:
1. Excellent electrical performance ensures long-term, stable operation.
The cable termination set in this kit employs highly resistant material made from cross-linked polyolefin (XLPO) and provides stress-control tube that helps electric field distribution becomes homogeneous. With this, the risk of the electric arc, and therefore insulation breakdown, is reduced.The product also withstood the 117 kV power-frequency withstand voltage test (5 minutes), 104 kV power-frequency withstand voltage test (4 hours) and ±200 kV lightning impulse withstand voltage tests (10 each for positive and negative). No breakdown or flashover took place during testing.
2. Superior sealing and protective performance, suitable for complex operating conditions.
The termination after heat shrinking tightly holds the cable end with minimum movement providing you with a durable layer which offers the necessary insulation, sealing and mechanical protection. It works very well in moisture, dust and dirt ingress prevention and it offers a high resistance against humidity, weathering and corrosion. The product has successfully gone through the 104 kV wet withstand voltage test and three-cycle thermal cycle (conductor temperature 95-100°C); all post-test checks have been carried out and no cracks or damage in any parts have been found which has proved that it is quite suitable for outdoor and industrial use under highly humid and hot conditions.
3. Efficient installation and broad applicability.
These types of heat-shrinkable cable terminations use a heat-shrink method in their installation and, after heating, they will snugly fit the cable. These terminations have no complicated installation tool and hence, allow for a quick installation as well as an easy maintenance; as such, the construction efficiency will be increased and the installation cost will be decreased. The product line is from 1kV (low voltage) to 36kV (high voltage) power systems, and they are suitable for both single-core and three-core XLPE power cables; besides, a tailor-made (OEM/ODM) service is provided to fulfill the specific requirements of the various projects.
Product Application Scenarios:
· Building Power Distribution Systems: The application in power distribution systems of residential buildings, commercial complexes and office buildings. It protects and stabilizes the cable connections for the terminal equipment.
· Industrial Manufacturing: Applied in industrial sectors such as factories, mining, steel, cement, and petrochemicals.
· Urban Power Grids: Used in urban distribution networks, ring main units (RMUs), box-type substations, and underground cable line terminations.
· Substations: Suitable connections in the realm of transformers, high voltage switchgear, GIS apparatus, and busbars, ensuring stable and reliable insulation and stress control for cable terminations.
· New Energy Sector: Used in projects such as wind power, photovoltaic power generation, and energy storage stations, meeting requirements for weather resistance, moisture protection, and insulation during long-term outdoor operation.
· Rail Transit and Infrastructure: Suitable for power distribution projects in subways, high-speed railways, airports, ports, and municipal infrastructure.
