XLPE cable & EPR Cable joint :
XLPE (Cross-Linked Polyethylene) cable and EPR (Ethylene Propylene Rubber) cable are two types of insulated power cables commonly used in electrical power transmission and distribution systems. Both types of cables are suitable for medium to high voltage applications and offer different characteristics and advantages.
XLPE Cable: XLPE cables have insulation made of cross-linked polyethylene, which is a thermosetting material. The cross-linking process enhances the mechanical and thermal properties of the insulation, making it more resistant to heat, moisture, and chemical substances. Some key features of XLPE cables include:
High Temperature Rating: XLPE cables can operate at higher temperatures compared to traditional PVC (Polyvinyl Chloride) cables. They have a higher thermal rating, typically up to 90°C or 105°C, depending on the specific design and application requirements.
Enhanced Electrical Properties: XLPE insulation offers excellent electrical characteristics, such as low dielectric loss, high insulation resistance, and low capacitance. This results in efficient power transmission and reduced losses.
Superior Mechanical Strength: The cross-linked structure of XLPE provides increased mechanical strength, allowing the cables to withstand higher mechanical stress, including bending, pulling, and external impacts.
Resistance to Environmental Factors: XLPE insulation is highly resistant to moisture, chemicals, and UV radiation. It provides good protection against environmental factors and ensures long-term reliability.
EPR Cable: EPR cables use Ethylene Propylene Rubber as the insulation material. EPR is a synthetic rubber with excellent electrical and mechanical properties. Some notable features of EPR cables include:
Flexibility: EPR insulation offers superior flexibility, making it suitable for applications that require frequent bending and flexing. It can withstand repeated movements without degradation.
High Thermal Stability: EPR cables have good resistance to high temperatures, typically up to 90°C or 105°C. The insulation material can handle elevated operating temperatures without significant performance deterioration.
Excellent Water Resistance: EPR insulation provides excellent water resistance, preventing moisture ingress and maintaining reliable electrical performance, even in damp environments.
Resistance to Chemicals: EPR cables exhibit resistance to various chemicals, including oils, solvents, and acids, which makes them suitable for installations in industrial environments where exposure to such substances is common.
Cable Jointing: Cable jointing is the process of connecting two cable ends together to form a continuous electrical circuit. It is necessary when extending or repairing cables, or when connecting cables of different types or sizes. Cable joints are typically made using specialized cable jointing kits that include components like connectors, insulating materials, and sealing compounds.
When joining XLPE or EPR cables, the jointing process involves several steps:
Cable Preparation: The cable ends are carefully prepared by stripping off the outer sheath and removing a portion of the insulation to expose the conductor cores.
Connector Installation: Connectors suitable for XLPE or EPR cables are installed on the prepared cable ends. These connectors are designed to provide a secure and reliable electrical connection.
Insulation and Sealing: Insulating materials compatible with XLPE or EPR cables are applied over the connectors and cable cores. These materials ensure electrical insulation and mechanical strength. Sealing compounds are also used to protect the joint from moisture and contaminants.
Joint Enclosure: Once the joint is completed and insulated, it is enclosed in a protective enclosure or sleeve to provide additional mechanical protection and environmental sealing.
Testing: After the jointing process, the joint is tested to ensure proper insulation resistance, continuity, and absence of any faults. Various electrical tests may be performed to verify the joint's integrity.
It is important to follow manufacturer guidelines and industry standards when performing cable jointing to ensure reliable and safe connections. Professional

Thanks
Good job
Thanks
Amazing work 👍
💕
Ap ki video's badi Helpful hoti🙃
Thankful 🥰
❤
Nice
It would be nice, if you could tell me the measurements
Measurement kitna lete hai..katne ke liye..aur copper Patti side kitna measurement lena padta hai..?
Jscer heat karne ke bad dono side black mastic marna hota hai aur canvass lagane ke bad dono side black mastic marna hota hai
Using not proper tools
Not using PPES...specially knife while cutting XLPE...very danger
There is no space between XLPE and ferrules after crimping....not accepted
Not used file after connecting each phase through ferrule to remove sharp edges
