C1 · Cable Accessory Kits

Product Overview

What C1 Does

Single core, 2 cores, 3 cores, 4 cores and 5 cores cable accessories. Suitable for protection of indoor and outdoor electric power cable joint and termination up to 1kV.

Complete 1 kV termination and joint kits for 1 to 6 core cable from 4 mm² to 400 mm² supplied as a single part number It is manufactured by Dalian United Polymer Material Co., Ltd. in Dalian China where radiation cross linking extrusion and molding are all performed in house under one quality system.

Key Benefits

One part number per cable configuration so purchasing and site stores stay simple
No cure time no mixing and no shelf life problem in cold or humid conditions
Sealed against moisture ingress at the gland the breakout and the lug barrel
A jointer with a gas torch and a knife can complete the work with no special tooling
Kits carry the same construction indoors and outdoors so training does not change per site

Who It Is For

Who Benefits Most from C1

The buyers and site teams this product was designed around

Distribution Network Contractors

Crews terminating 1 kV feeders in street cabinets pillar boxes and distribution boards need one carton per joint rather than a shopping list of loose parts.

Panel Builders and Switchboard OEMs

Incoming LV cable terminations inside assembled panels have to be repeatable across production batches and traceable for the type test file.

Building Services and Facility Contractors

Riser cables submains and generator tails in commercial buildings where a jointer works in a shaft with no space for a bulky resin mould.

Solar and Storage EPC

DC and AC collection cable between combiner boxes inverters and LV transformers where hundreds of identical terminations are made in a few weeks.

Problems It Solves

Problems This Product Removes

Every one of these is a failure mode we have seen on real networks

Loose Part Kitting Wastes Hours on Site

Buying tube boots lugs and mastic separately means a jointer discovers a missing item at the bottom of a trench. C1 ships every consumable for one termination or joint in one bag with a pack list.

Resin Joints Need Cure Time and a Level Surface

Two part resin will not cure reliably at low ambient temperature and cannot be re-entered. A heat shrink joint is energisable as soon as it cools.

Multi Core Breakouts Are the Usual Failure Point

Water tracks into the crutch of a 4 or 5 core cable. C1 kits include a molded breakout boot with adhesive on the big end and every leg.

Mixed Conductor Sizes on One Project

Six conductor bands from 4 to 400 mm² and six core counts means one product family covers a whole LV network rather than five suppliers.

Application Scenarios

Where It Is Used

Street Cabinets and Pillar Boxes

Terminating 4 core 95 to 240 mm² XLPE service cable where the enclosure is small and damp.

Submain and Riser Terminations

Building risers where 5 core cable enters a distribution board and the breakout must be sealed.

Straight Through Joints in Duct

Repairing or extending a 1 kV feeder inside a duct where a resin mould will not sit level.

Generator and UPS Tails

Flexible and armoured tails at generator sets where vibration and heat cycling attack a taped joint.

Solar AC Collection Circuits

Repeated identical terminations at inverter stations and LV combiner cabinets.

Manufacturing and Quality

How It Is Made and Checked

Compounding extrusion radiation cross linking expansion and test all under one roof in Dalian

01
Compounding

Base polyolefin antioxidants flame retardants and functional fillers are mixed to a recipe held under our own formulation control rather than bought as a masterbatch.
02
Extrusion

The compound is extruded to the required wall and diameter. Co extruded products form two or three layers in a single pass so no interface can trap air.
03
Radiation Cross Linking

Electron beam irradiation creates the cross linked network that gives the material its shape memory. This step is what makes the product heat shrinkable.
04
Expansion

The cross linked part is heated expanded to its supplied diameter and cooled under tension so the expanded shape is locked in until heat is applied again.
05
Test and Inspection

More than 90 percent of product performance tests are carried out in our own laboratory including tensile elongation heat aging dielectric strength and tracking resistance.
06
Packing and Traceability

Each batch carries a production record so a delivered part can be traced back to its compound lot and process parameters.

Extrusion and irradiation workshop at the UPM Heat Shrink factory in Dalian China — Extrusion and processing workshop in Dalian. Line side inspection stations let an operator check wall thickness and concentricity without stopping the run.

Use Guide

How to Select and Install C1

The sequence our engineers walk customers through on every first installation

01
Confirm the Cable Data

Record voltage class conductor cross section in mm² core count insulation type and whether the position is a termination or a joint.
02
Pick the Part Number

Read the selection table below. Terminations start NSY and joints start JSY. The last digits encode core count and conductor band.
03
Prepare the Cable

Strip the outer sheath to the length on the kit instruction sheet remove armour bedding and clean the core insulation with the supplied wipe.
04
Fit the Breakout and Cores

Slide the breakout boot to the crutch then shrink from the centre outward so trapped air is driven ahead of the flame.
05
Crimp and Insulate

Crimp lugs or connectors then apply the insulating tubes with a soft yellow flame moving constantly around the circumference.
06
Finish and Check

Confirm adhesive has flowed at every end and that no wrinkle or burn mark remains then allow the joint to cool before energising.

FAQ

C1 Frequently Asked Questions

The questions buyers ask before they place an order

Which part number do I need for a 4 core 185 mm² cable termination

185 mm² sits inside the 150 to 240 mm² band and 4 core is series 14 so the termination is NSY-143 and the equivalent joint is JSY-143. Send us the cable datasheet on WhatsApp and we will confirm before you order.

Is the kit complete or do I need to buy lugs separately

The standard C1 kit contains the tubing breakout boots mastic and cleaning materials. Lugs and connectors are offered as an option because most utilities specify their own brand and barrel length. Tell us your preference when you enquire.

What is the electrical test the kit is designed to pass

C1 is designed for 4 kV for 1 minute power frequency withstand plus a three cycle load test at 5 hours heating and 3 hours cooling with the conductor at 75 °C followed by 2.4 kV for 4 hours with no breakdown and no flashover.

Can the same kit be used indoors and outdoors

Yes. The C1 construction uses non tracking outer material and adhesive lined seals so the same kit is used in a cabinet a duct or open air. For heavily polluted outdoor sites we recommend adding Y3 rain sheds.

What is the minimum order quantity

Standard kits ship from stock in small quantities for trials. Production orders are normally quoted per 50 or 100 kits per part number. Mixed part numbers on one order are accepted.

How long does production take

Kits held in standard configuration ship in 5 to 10 working days. Fully custom kit contents including private label printing run 15 to 25 working days.
